Question about SourceDataLine to Mixer

At what point is the audio data decoded (if needed)? Is it decoded as the AudioInputStream reads it, when the SourceDataLine writes it, or when it hits the mixer? I am curios because I am getting a weird buffering problem that I believe I can trace back to the decoder, but can not be certain because I am not 100% at what point the mp3 file is decoded. Thanks

Satellite L20-101: Question about memory modules mixing PC2-4300 and PC2-4200

Hello
I have Toshiba Satellite L20-101. It has onboard 512MB RAM (PC2-4300). Today I added another RAM module but this new module is PC2-4200. Is there anything wrong doing this? Both modules are DDR2 and 533MHz and 512MB.

Hi Pawel,
In principle there is no problem with mixing RAM modules of slightly different types but normally the total RAM will only run at the speed of the slower module. If your notebook recognises the correct amount of RAM from both sticks then there will ne no problem.

Hi All, I have question about the iMac operating system. I have the last updated. The problem when I manage the place of the folder windows they are all mixing up. I mean they not on the place where I left them. how to set they stay on the same place? I know there are different possibilities to set.
I tried but it not helped for me. What I can do? How and where can set this they stay on their place?
Thanks.

Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In Library Manager it's the FIle -> Rebuild command)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

Some questions about a Time Capsule

Hi!!
I just have a few questions about a Time Capsule, but first let me explain the backgroud to my questions.
I live in a 2 floor house(including a basement) and my bedroom is downstairs. My parents currently have a desktop PC connected to our wireless router and our printer. Me and my step-father both have 13 inch MacBook Pros, and he uses the Mac like a basic computer, so the equipment connected to our PC is good for him. I, on the other hand, use my Mac, iPad and iPhone to their fullest potential. I am a SUPER MEGA NERD when it comes to computers, so I plan on making my bedroom an amazing office at the same time. So I want an AirPrint Enabled printer in my bedroom (Under 100$$) along with a Time Capsule to back up my information, because everyday I look around in the backdoor of my Mac alot, and if I jack anything up (And I cant handle the problem) I would like to restore my Mac to a previous version. So here are my questions:
1) My bedroom is right underneath our router, so i get GREAT Wi-Fi in my room. If I get a Time Capsule, can I use it in my room to extend my Wi-Fi, and how would that work? Will it extend my wifi under the same name, because I would like my own Wi-Fi (Titled to what I want with my own password)
2) If I have to create a NEW Wi-Fi network, how would I do that?
3) Would I need to connect my new printer directly to my ROUTER, or could I connect it to the TIME CAPSULE?
If you don't understand what I'm trying to ask (Even though I feel like it's self-explanatory)
ONE question about the PRINTER: Do any of you have any recommendations for an AirPrint Enabled printer under 100$? Even under-150$ would be okay.
THANKS FOR ANY HELP!!!!

everyday I look around in the backdoor of my Mac alot, and if I jack anything up (And I cant handle the problem) I would like to restore my Mac to a previous version. So here are my questions:
Don't just depend on TM.. use a disk image type utility.. either one of the Mac tools, SuperDuper, CCC, Chronosync or even a linux boot cd (if you have a cd/dvd drive still or via usb can boot) a great tool is Clonezilla.. it will do basically any computer, Mac, Linux, Windows.. and since it boots into its own OS can restore a computer in a flash. Then you can add the incremental changes from TM.
1) My bedroom is right underneath our router, so i get GREAT Wi-Fi in my room. If I get a Time Capsule, can I use it in my room to extend my Wi-Fi, and how would that work? Will it extend my wifi under the same name, because I would like my own Wi-Fi (Titled to what I want with my own password)
Actually I am surprised you get good wireless as usually directly above or below a router is often the worst spot. Time Capsule cannot extend the wireless of any other router than Apple.. it is a special system and only Apple can join the club. It has bad effect though, if you set the TC to extend wireless it turns off ethernet ports.. which is hugely dumb.
The best arrangement is ethernet to the upstairs.. or EOP adapters. If not then a wireless router that matches the existing unit will generally be better than mixing apple and non-apple.
2) If I have to create a NEW Wi-Fi network, how would I do that?
3) Would I need to connect my new printer directly to my ROUTER, or could I connect it to the TIME CAPSULE?
You create a new wireless network by selecting manually the wireless channel and use different wireless name, ssid and security. There are 3 available channels on 2.4ghz.. your existing router will use one or two.. depending on if the setting is 20mhz or 40mhz.. so you need to manually set everything and not use auto.
TC is slow on 2.4ghz cf 5ghz and there are many more channels at 5ghz but not everything can use it.. iphone for instance is 2.4ghz only . whereas ipad can use 5ghz.. most full computers now can use 5ghz.
Buy a wireless network printer. Or alternatively an ethernet network would be also ok but now are more expensive than wireless ones. Network printers are not much more than straight USB and work much better.
I do not use airprint so have nothing to offer.. find the best HP model in your budget.. but others may have had more experience.. I use ethernet connected b/w laser business type HP.. they work great.. but airprint is too recent an innovation for me.

Questions about editing with io HD or Kona 3 cards

My production company is switching from Avid to Final Cut Pro. I have a few editing system questions (not ingesting and outputting, just questions about systems for the actual editors - we will have mac pros with either kona 3 or io HD for ingest and outputs)
1) Our editors work from home so they most likely will be using MacBook Pros - Intel Core 2 Duo 2.6GHz 4GB computers with eSata drives to work on uncompressed HD, will they be able to work more quickly in FCP if they are using the new Mac Pro 8-Core (2 Quad-Core 2.8GHz Intel Xeon) or will the mac book pro's be able to hold their own with editing hour long documentaries, uncompressed HD
2) Will having an AJA Kona 3 (if we get the editors mac pros) or io HD (for the mac book pros) connected be a significant help to the editor's and their process, will it speed up their work, will it allow them to edit sequences without having to render clips of different formats? Or will they be just as well off without editing with the io HD?
I'm just trying to get a better understanding of the necessity of the AJA hardware in terms of working with the editors to help them do what they have to do with projects that have been shot on many formats- DVCPro tapes, Aiptek cameras that create QTs and P2 footage.
Thanks

1. with the IoHD, laptops become OK working with ProRes and simply eSata setups. Without the Io, they can't view externally on a video monitor (a must in my book). It will not speed up rendering a ton, nor will it save renders of mixed formats. The idea is to get all source footage to ProRes with the Io, and then the Io also lifts the CPU from having to convert ProRes to something you can monitor externally on a video monitor, and record back to any tape format you want... all in real time.
2. Kona 3's on Towers would run circles around render times on a Laptop... no matter what the codec, but the Kona does not really speed renders up. That's a function of the CPU and just how fast is it. (lots of CPU's at faster speeds will speed up render times).
I'd recommend you capture to ProRes with Io's or the Kona 3 and don't work in uncompressed HD. You gain nothing doing it quality wise at all. And you only use up a ton of disk space (6 times the size in fact) capturing and working in uncompressed HD, which from your post, you're not shooting anyway. The lovely thing about ProRes is that it's visually lossless, efficient, and speeds up the editing process. Mixing formats can be done, but it's better to go to ProRes for all source footage, and edit that way.
With either the Kona or the Io, you then can output to uncompressed HD tape... that's what they do for you no matter what codec you've edited in. ProRes is designed to be the codec of choice for all HD projects when you're shooting different formats especially... Get them all singing the same tune in your editing stations, and you'll be a much happier camper. Only reason to buy laptops is portability... otherwise you're much better off with towers and the Kona 3 speed wise.

Question about DBCA generate script o create RAC database 2 node cluster

Question about creating two node RAC database 11g after installing and configuration 11g clusterware. I've used DBCA to generate script to create a rac database. I've set
environment variable ORACLE_SID=RAC and the creating script creates instance of RAC1 and RAC2. My understanding is that each node will represent a node, however there should only be one database with a name of 'RAC'. Please advise

You are getting your terminology mixed up.
You only have one database. Take a look, there are one set of datafiles on shared storage.
You have 2 instances which are accessing one database.
Database name is RAC. Instance names are RAC1, RAC2, etc, etc.
Also, if you look at the listener configuration and if your tnsnames is setup properly then connecting to RAC will connect you to either one of the instances wheras connecting to RAC1 will connect you to that instance.

A few questions about Patone colors

I have a few questions about patone colors since this is the first time I use them. I want to use them to create a letterhead and business cards in two colors.
1)
I do understand that the uncoated is more washed out than the coated patone colors. I heard that this is because the way paper absorbs the inkt. This is why the same inkt results in different colors on different paper (right?). My question is why is the patone uncoated black so much different than normal black (c=0 m=0 y=0 k=100) or rich black:
When I print a normal document with cmyk, I can get pretty dark black colors. Why is it that I cannot have that dark black color with patone colors? Even text documents printed on a cheap printer can get a darker color than the Patone color. It just looks way too grey for me.
2) For a first mockup, I want to print the patone colors as cmyk (since I put like 10 different colors on a page for fast comparison). I know that these cmyk colors differ from the patone colors and that I cannot get a 100% representation. But is there a way to convert patone to cmyk values?
I hope that some of you can help me out with my questions.
Thanks.

You can get Pantone's CMYK tints in Illustrator, (Swatches Panel > Open Swatch Library > Color Books > PANTONE+ Color Bridge Coated or Uncoated) but in my view, what's the point? If you're printing to a digital printer, just use RGB (HSB) or CMYK. Personally, I never use Pantone's CMYK so-called "equivalents."
Pantone colors are all mixed pigmented inks, many of which fluoresce beyond the gamut limits of RGB and especially CMYK. The original Pantone Matching System (PMS) was created for the printing industry. It outlined pigmented ink formulations for each of its colors.
Most digital printers (laser or inkjet) use CMYK. The CMYK color gamut is MUCH SMALLER than what many mixed inks, printed on either coated or uncoated papers can deliver. When you specify non-coated Pantone ink in AI, according to Pantone's conversion tables, AI tries to "approximate" what that color will look like on an uncoated sheet, using CMYK. -- In my opinion, this has little relevance to real-world conditions, and is to be avoided in most situations.
If your project is going to be printed on a printing press with spot Pantone inks, then by all means, use Pantone colors. But don't trust the screen colors; rather get a Pantone swatch book and look at the actual inks on both coated and uncoated papers, according to the stock you will use on the press.
With the printing industry rapidly dwindling in favor of the web and inkjet printers, Pantone has attempted to extend its relevance beyond the pull-date by publishing (in books and in software alliances, with such as Adobe) its old PMS inks, and their supposed LAB and CMYK equivalents. I say "supposed" because again, RGB monitors and CMYK inks can never be literally equivalent to many Pantone inks. But if you're going to print your project on a printing press, Pantone inks are still very relevant as "spot colors."
I also set my AI Preferences > Appearance of Black to both Display All Blacks Accurately, and Output All Blacks Accurately. The only exception to this might be when printing on a digital printer, where there should be no registration issues.
Rich black in AI is a screen phenomenon, unless in Prefs > Appearance of Black, you also specify "Output All Inks As Rich Black," -- something I would NEVER do if outputting for an actual printing press. I always set my blacks in AI to "Output All Blacks Acurately" when outputting for a press. If you fail to do this, then on the press you will see any minor registration problems, with C, M, and Y peeking out, especially around black type. UGH!
Good luck! :+)

Questions about Audigy 2 ZS connecti

Hello,
New to these forums, so bear with me. I'm considering purchasing an Audigy 2 ZS gamer card, and have some questions about the card and speaker setup. I've read the FAQ's in the forum, and they have been a big help, but I still have questions related specifically to my setup. Here's the system specs:
AMD Athlon 64 3000+
Asus K8V SE Deluxe
VisionTek Radeon X800 XT PE
Seagate 250 gig SATA HDD
gig Crucial ram
Antec P80 case
Antec TruePower 430 ps
Altec Lansing ADA885 digital speakers (awesome sound)
Altec Lansing headset (cheap but works for voice and gaming)
ADI AD980 onboard sound
Windows XP Home
. I currently am able to run both the speakers and headset at the same time by using the front panel audio outlets on the case (helps with the immersion in IL2 946). I would like to continue doing this(using front panel audio) with the new card. I've found several places that have an adapter cable for sale, http://www.x-tap.com/
http://www.performance-pcs.com/catal...oducts_id=2700
http://ask.americas.creative.com/SRVS/CGI-BIN/WEBCGI.EXE?New,Kb=ww_english_add,U={B8F6030-DA4F-D3-94F4-00500463020E},Company={CEAE26D-879-4C00-AC9F-03BC258F7B70},d=3025443648,VARSET=ws:http://us.creative.com,case=5764
The plug that I have has only 3 separators, not 4. Will this work with the Audigy 2? I don't have a link for this plug, unfortunately.
4. I had been considering purchasing? a set of USB headphones, but I've been told that when you plug them in, the sound is cut off for the speakers. If there was a workaround for this, I might consider getting them. Then I wouldn't have to use the front panel audio or the connections on the card.
5. I've heard of an issue with this particular set of speakers and the Audigy 2 card, particularly that the speakers were originally designed for a Dell system, and the wiring was phased differently than in other systems. Is this something to be concerned with, and if so, is there a workaround?
I like to research a particular product before I buy it, in order to make an informed decision and avoid problems if possible. Sometimes it works, sometimes it don't
Thanks in advance for the help.

The inputs are easy to find and select:?
Right-click the Mixer icon on the taskbar and select "Playback Devices".<
There should open a new Window with the options of "Speakers" and "SPDIF"<
With Speakers highlighted click the?"Properties" button on the lower?right corner<
Go to the 4th tab (I believe it is "volume" in english, "Pegel" in german)<
There you have your inputs!<
Unmute Line-In and set its volume according to your desires.<
Also remember that software designed for XP, that should control the Line-IN settings, (ie. Hauppauge WinTV or Dscaler) will be unable to do so in Vista, do to the architecture change. You can however enable "Compatibility Mode for Windows XP SP2" for these applications (right-click on their executable) and restore control of the inputs directly from the program. (You should however unmute it first as explained above). PS:? All Creative Software that came on the CD is incompatible to Vista. Only the included Audio Console should work as expected.Message Edited by alexs3d2 on 05-07-200707:3 PM

Some random questions about integration features

Greetings,
after working for a few weeks with Autovue's ISDK (web server) and having some sucess with its integration with our custom CMS, I have a few random questions about what can be done and what can't be done. So, instead of opening many new threads, I'll post them here together.
1) Translation. We are localised in Russia, and its translation is incomplete. I have found a tra_en.properties file in AutoVue/bin, and a description about how to create a properties file for custom actions. But no information about how to translate to other languages - and russian translation appears to be packed within the jar of the applet. Is there a clean way to translate, or refine the current translation, so we don't get a mix of russian and english commands in the applet? Because my tries using EXTRABUNDLES have failed, as I don't want to add a bundle for extra actions, but to replace it for existing ones.
2) Attachments in markups. Markups allow to attach other files, but since our CMS is custom, we only get the option to attach files from our local drives. We did no browse integration with the CMS, as people with different levels of permission will have different access to files there, and we considered unnecessary to provide that level of integration. We are considering to remove this action from the GUI, but before that I'd like to evaluate how hard would it be to generate an upload file action, so the attached file would be stored in the custom CMS and linked to it so the whole thing worked. My guess is "it will be hard and time consuming", so for now, we are considering to delete this feature in our integration.
3) Is there a way to resize the Open markup dialog? We have several properties displayed, and fit well within a standard screen, but the dialog is small and you have to scroll the table to see all properties.
Thanks for any assistance with these issues

As always, thanks for the fast answer, Artash.
Yes, now I see attachments are stored inside the markup file. The problem is, when I open markup mode for the attachment, since the attachment uses some kind of default access method, my url's from the integration with the background CMS are broken completely. I believe the ideal state here would be to make some kind of inner markup for the attachment, maybe stored within the original markup file along the attached file. Or maybe it works that way, and I need to access it with the default gui action instead of my custom one. If that is the case, is there any way to tell the gui file how to differentiate a standard opened file from an attached one? If so, the issue has solution. If not... Well, then maybe something escapes me.

Question about upgrading iTunes multiple computers with shared library

Greetings,
I have a question about upgrading to the current version of iTunes.
Currently, my household uses 3 Mac computers (2 Powerbook 17in laptops and a Mack Mini). We are all (currently) on system 10.4.11 (with iTunes 9.2.1). Between the 3 computers we have a shared iTunes music and video library on a networked high capacity hard drive.
We recently purchased an iPad. In order to make it easy for updates and to use media from our iTunes shared library I decided that we should upgrade the systems on our home computers to Snow Leopard. I have ensured that all the computers have at lease 2 Gb of RAM and adequate hard drive space.
The only possible problem I see is that one of the Powerbook laptops uses the old Motorola processor. (This is one of the last Powerbooks to use that processor.) I don’t think this computer can be upgraded to Snow Leopard.
My question is, if I upgrade 2 of the computers (and iTunes in the process), will I still be able to access the shared iTunes library using the older computer with the older system and iTunes? Will the upgrade process change the iTunes library in such a way that the one older computer will no longer be able to properly access that library?
Are there any other problems I might encounter having a mixed system/iTunes environment?
Thank you,
Tim

Just a thought. Should I somehow open iTunes on MBP2 using MBP1's Library file??
both Macs can access the same library file, however, only one at a time !
to do that, you would ideally have the entire iTunes folder (not just the iTunes music folder) on the external. then, on one Mac after the other, launch iTunes while holding the option key, click on +choose library+ when prompted, and select the iTunes folder on the external.
or, you could have two separate libraries and keep those in sync using third party tools such as Syncopation, TuneRanger or SuperSync.
for purchases from the iTunes store, you could set up _*Home Sharing*_ - it can be configured to automatically transfer new purchases to home shared libraries.
Can I create a script to have MBP1 always save the iTunes Library file on the shared hard drive?
no need.

CFC's - Question about coding guidelines

I have a question about the following section in the
CF
Coding guidelines
quote:
{cfmxroot}
---wwwroot/ » web-accessible .cfm pages and .cfc Web
Services
---extensions/
--------components/ » tree for .cfc files
--------customtags/ » tree for .cfm custom tags
--------includes/ » tree for include files
---config/ » tree for configuration files
This implies that we have two Custom Tag Paths set up in the
CFMX Administrator:
{cfmxroot}/extensions/components/
{cfmxroot}/extensions/customtags/
We also have mappings for the root of the includes tree (for
cfinclude) and the custom tags tree (for cfimport):
/cfinclude » {cfmxroot}/extensions/includes/
/customtags » {cfmxroot}/extensions/customtags/
1. Why would you want to add both a custom tag path
AND a mapping for " {cfmxroot}/extensions/customtags/"?
2. The guidelines seems to imply you should use a custom tag
path for components, instead of a mapping. If the "components"
directory is already outside the webroot, then adding a CF mapping
shouldn't make it web accessible, right? So is there any benefit to
using a custom tag path versus a mapping?

It is up to you where you put your components and where you
put your custom tags. The standard way, as I know it, at least, is
to create a mapping for your cfc directory on the
Mappings page of the Coldfusion Administrator and to
register the path to your custom tag directory on the
Extensions/Custom Tag Paths page. In answer to your first
question, you will also need to create a mapping for a custom tag
directory if you intend to call tags using the template-attribute
of cfmodule.
Coldfusion considers the directory-path that you register on
the
Extensions/Custom Tag Paths page an absolute path. That is
what enables you to call a tag directly by name on any page of your
application, for example,
<cf_myCustomTag>.
One consequence is, if you stored a component myComp.cfc in
such a directory, you could instantiate it on any page simply by
running
<cfset myObj = createobject("component","myComp")>
However, this doesn't offer anything a mapping wouldn't. So,
in answer to the second question, I don't think one should use a
custom tag path for components. Mixing one's custom tags with one's
components only produces an oil-plus-water structure.

Question about printing by page count

Hi
I'm new to this and I have a question about printing our invoices by page count.
We generate our invoice using Crystal 2008 we have invoices that can range from a single page to as many as 6 pages. I would like Crystal to preview/print the reports in order of how many pages are in the report. Example: print all single page invoices first then all invoices that are 2 pages and so on. Is this possible?
Thank you in advance

Hi Ido,
Thanks for your input. This is more or less what Carl was suggesting yesterday and I gave it a lot of thinking. The problem here is that I cannot go with "good enough resolution" - I need perfect resolution.
The reason for this apparently silly requirement (why would one sort a bunch of invoices by number of pages instead of Customer Number, as long as they end up in an envelope anyway?) is the proposed purchase of a folding/stuffing machine which could do very fast what now takes one person 4 days to achieve.
One type of machine comes with three settings - fold/stuff 1, 2 or 3-page statements. You need to have three stacks with all the statements that have 1, 2 and 3 pages. The ones with more pages will have to be folded manually, but there are only about two dozen clients that give us that much business. You feed the machine one stack at a time and set it to process the respective number of pages. Any statement that falls accidentally in the other stack will either cause the whole rest of the stack to be mixed up, which is very bad, or cause one customer to receive his invoice and someone else's, which is just embarrassing. I cannot afford any of these scenarios.
Given that the statement contains variable-length (and depth) messages that vary by month and by profit center, and it could also contain one or more groups of details, each with its own header, it is very risky to try to come up with magic numbers attempting to estimate the number of pages based on the number of detail lines. Someone will still have to eyeball very carefully the initial stack of statements in the areas where the number of pages increases by one and make sure that ordering by number of detail lines did not mix, for example, one report with two pages among two reports with one page. Of course, this increased scrutiny will be necessary only around the areas where the page number transitions from 1->2, 2->3 and 3->4, which is much better than trying to order by number of pages all 1500 statements, but still depends on one's manual intervention and focus and, as a result, makes me pretty uncomfortable.
I have taken a look at the "Group Sort Expert". If you select the "All" option (all groups) and you had some kind of summary value then you could sort the report by that value. The idea was to create a hidden Average field over the TotalPageCount runtime variable (which will always equal the TotalPageCount for that customer, since it's the same for all the pages in that group) and use that summary field in the "Group Sort Expert", which would have solved the problem elegantly. Unfortunately, there is no way to create a summary field over a runtime variable. I even created a formula that just returns the TotalPageCount, but that formula did not show up in the list of fields available for summarization (while other formulas did).
It looks like the reporting engine does not allow this type of "late-sorting". I wonder if it is possible at all, because in effect this would require the engine to execute an additional pass: first it should somehow generate the whole report grouped by Customer Number so it knows how many pages are in each group, then it should sort by the number of pages and only after that it could render the report. I'm not sure the engine can do this additional pass.
I would be very curious to hear about the other (more complex) ideas you mentioned. For example, I have seen (in Crystal 2008) a checkbox allowing "sorting by a formula". I don't know how to write a formula used in sorting, but the basic question in the paragraph above still stands: does the engine even support such a feature?
Thanks again.

Design question about SNASw, DLSW and VDLC

Hello,
I have a question about Ethernet redundancy in an APPN environment.
Let's have an example with 3 routers running SNASw that are on the SAME LAN (no vlans) as the Mainframe's OSA (one OSA only). APPN is configured on the Mainframe.
Using DLSw+, all downstream PUs are connected to the 3 routers. Can I define in the VDLC interface of each router the SAME MAC address, and this MAC address be the destination MAC of the downstream PUs?

Hi,
yes, headend routers are the ones in front of the OSA/mainframe.
If you replace a tokenring with ethernet in the data center/headend, than the snasw dlsw solution is almost perfect for you. If you use hpr/ip to connect upstream to the host you are all set.
In that case you dont advertise any mac addresses on the local ethernet between the snasw/dlsw routers and the osa since it is hpr/ip. Basicaly ip routing only.
From the clients perspective, they dont really know that there is a change since you replicate the old tokenring mac address as vdlc mac address/snasw port and the end systems still connect to them like they did before.
In respect to dlsw ethernet redundancy we have to be a bit carefull not to mix the scenarios.
Dlsw ethernet redundancy is designed for the branch. Not the data center.
If you use dlsw ethernet redundancy with ethernet switches, and in almost all cases today ethernet means ethernet switches, you configure a mac address mapping between artificiall local mac addresses and your real remote mac address of the host.
On each router you configure a unique local mac address. Than you point half of your end systems dmac to the local mac address configured on router1 and the other half to the local mac address configured on router2. That way you achive load balancing.
The two routers exchange their mapping and in case router1 looses the connection to router2, router1 will activate the mapping it learned from router2 aswell and then take over those circuits additional.
If you decide that you configure on router1 the local mac address equal to the remote mac address, because you have a large number of clients and can not simply change the damc's on all of them, than you need to configure a "dummy" mapping on router2 and router1 will get all the circuits in this example. router2 would be purely for redundancy in case router1 goes down.
If you think about this than it is clear why dlsw ethernet redundancy is designed for the branch. In the branch we map local to remote mac addresses and the remote mac addresses are the hosts. Typically there are only a limited number of host mac addresses to map.
If you turn this around and put dlsw ethernet redundancy on the host end than you have to map all clients. If you have only one or two clients this is certainly doable. But if you have a large nuber of clients this is simply not manageable.

I am an HP employee.

My HP, purchased in June 2012, died on Saturday. I was working in recently installed Photoshop, walked away from my computer to answer the phone and when I came back the screen was blank. When I turned it on, I got a Windows Error Recovery message. The computer was locked and wouldn't let me move the arrow keys up or down and hitting f8 didn't do anything.
I'm not happy with HP. Any suggestions?
