Buffer Underrun Protection - Simple Question

Hello. I've searched this forum (and Roxio's) for about an hour, and I can't find a simple answer to this question.
I know that to create a stable DVD for replication, I should have Lossless Linking turned OFF. Yet, if I burn using Toast (which many on this forum recommend), should the "Buffer Underrun Protection" be turned on or off?
The wording in the manual is very ambiguous. Can anyone that knows please spread the wealth?
Thanks
PowerPC G5 Mac OS X (10.4.8)

Buffer underrun protection should be on normally to prevent bad burns, have not heard of it being an issue, maybe someone else here has more info,
Make sure you also speak to the replicator on how they want the DVD prepared.

Device drained its buffer w/out burn underrun protection

I've been trying to burn one of my playlists from itunes, but after a minute or so, the message "The device drained it's buffer w/out burn underrun protection" appears, and the blank CD is ejected, with no tunes burned.
I've never had a problem burning playlists before, and I have no idea what this message means, nor how to correct the problem. Help! please.

Cyd,
To even get started on resolving this issue, you and the others having the problem should all report (by posting here) the version of iTunes you are using and which built in external media drive your Mac has. I for example have an eMac with Combo drive and iTunes 4.7.1.
I just ran across your post and "looked in" - so I promptly composed a new playlist and burned it to Maxell CD-R, 700 MB disk. It worked flawlessly.
I've checked (as you probably have) every item on the iTunes Preference Panel and can't find anything about buffer size EXCEPT in "Advanced" under the streaming internet radio panel (or "window"). There is a buffer size selection of "small, medium, large."
I see no indication that there's a connection between that and the "other" buffer which is for under-run protection. (Using Toast Titanium, there's a very clear arrangement of menus, including one for setting {disk burning} buffer size.)
So I'm stumped too - except to suggest you try setting the streaming buffer to "large" just in case it's a "dual control" for the burning buffer also. Mine's set at Medium, by the way.
Can't resist mentioning - I think your screen name is fantastic, I'm old enough to remember the lovely dancer / actress, Cyd Charisse.

"The device drained its buffer without burn underrun protection"

I see so many postings about this but no answers?!?!
I am trying to burn a movie made with iMovie HD to a dvd with my superdrive (details on the drive below). The DVD is Office Depot generic (not the best I know) DVD-R media. I have tried burning it with Dragon Burn and the mac disk utility, and keep getting the same error:
"The device drained its buffer without burn underrun protection"
How do I fix this? The movie is a 1.7 gig .img file . I have also tried burning it straight from iDVD and to know avail, same error. Suggestions?
Here is my drive info.
SONY DVD RW DW-U10A:
Manufacturer: SONY
Model: SONY DVD RW DW-U10A
Revision: A43h
Serial Number: EAB86043
Drive Type: CD-RW/DVD-RW
Disc Burning: Apple Supported/Shipped
Removable Media: Yes
Detachable Drive: No
Protocol: ATAPI
Unit Number: 0
Socket Type: Internal

Welcome to iDVD Discussions.
How do I fix this?
Suggest you create a disc image and then burn the DVD. File/Save as Disc Image...
http://docs.info.apple.com/article.html?path=iDVD/6.0/en/18.html
http://www.kenstone.net/fcphomepage/image_to_diskstone.html
This will isolate any encoding/burning issues you may encounter. Once the disc image is created, double-click the .img and burn the virtual disc that should appear on your desktop, using Toast to burn the DVD. Disk Utility to burn the .img file. Usually, you can select a burning speed in Disk Utility.
There are variations to this process based on which OS X you are using...
Open Disk Utility (in Utilities folder in Applications folder), click on the virtual disc (maybe the .img) in the left-hand window. Click the Burn icon. A new window should drop down and your SuperDrive tray will open after clicking the Burn icon. Insert a recordable DVD. (Verbatim DVD-R preferred by me.) Click the Close button. Wait. Select a burn speed. If you hold your mouse cursor over the pop-up it says: "Select a slower speed to work around burn failures," so select 4x or slower for best results. Then click the Burn button.
-->If the virtual disk selection won't allow you to click the Burn icon, use the .img file instead. This may have changed in 10.3.9 and did change in Tiger.
Also, you can use DVD Player to play the virtual disk to check your iDVD project before burning to DVD. Launch DVD Player. File/Open VIDEO_TS (Open DVD Media... in Player 4.6). Find the VIDEO_TS folder and open that. (The audio folder is for DVD-Audio disks.)

Formatting Error.. illegal request...Buffer Underrun

Hi All..
I'm having trouble burning an FCP 5 to DSP 4. I have correctly exported the files to Mpeg-2, using both the File--Export--QuickMoive etc, and/or using Compressor.
I usually get(something like this)
Fomatting Failed. Unable to format disc, illegal request. Buffer Underrun (0x21, 0x20).
I even tried using idvd instead and it happens there also..
Out of 15-20 Tries with new DVD's each time, it only burned twice. Of those the disc would play but none of the menus worked(that could be a me problem, not linking an assest right)
Is this a Super Drive failure, Hardware Failure
I'm going to try the file on campus, and see if I can burn it there on a different MAC.
I'm sorta new to the Mac Universe, so any guidance would be helpful.
Oh yeah, I'm using a Dual Core 2.0 GHZ G5, with a 1GB of Ram, upgraded Graphic card, Latest Tiger...etc

Are you doing anything else on the Mac whilst you are burning - network access, Internet surfing, screen savers, energy savers of any kind - anything that will demand CPU processing power? If so, don't!
This question came up just about a week ago - run a search for buffer underrun in the forum. The situation occurs when the DVD writer is left waiting for data to be sent to it... it's buffer runs out of data. This is usually caused by the main processor being used by some other process and not being able to keep a steady stream of data being sent to the writer.

Simple Question - loginblock.ascx

Hi,
I apologize in advance for what I'm sure is a simple question!.
I'm not familiar with C# at all and am pretty new to ASP.NET, therefore I'm keeping the level of customization to a minimum during phase 1 of our website. However, I would like to add a remember me checkbox to the loginblock.ascx. I have followed the normal asp rules for adding this checkbox to the layouttemplate but it makes no difference to whether a user is remembered. Looking at the code it would seem that the remember me value is always passed as false:
protected void loginMain_LoggedIn(object sender, EventArgs e) {
        NPUser user = new NPUser(loginMain.UserName);
        ((NPBasePage)Page).Login(user.UserID, user.AccountID, false);
All I would like to do therefore is control that value with a checkbox, so I thought this code would work:
protected void loginMain_LoggedIn(object sender, EventArgs e) {
        NPUser user = new NPUser(loginMain.UserName);
        ((NPBasePage)Page).Login(user.UserID, user.AccountID, checkbox1.Checked);
It doesnt, the control no longer loads. As a matter of interest I replaced checkbox1.checked with other controls on the page, and with the exception of the login and main panels, none of the other controls could be referenced either without generating an error. I'm obviously missing something fairly fundamental here, and would appreciate any help.
Thanks!.

I have manually changed the value to true, and it triggers the process that automatically logs a user on at the next visit.
This is currenty where my checkbox resides, although it I have moved it around to see if it made any difference!.

Audigy 4 and Reciever/Amp simple question

Hi all,
Despite inundating myself with what is probably TOO much information from the knowledge base and forum, I could really do with an answer to what is essentially a pretty simple question....
I recently got an Audigy 4 sound card and external io hub. Lovely bit of kit. Very nice. I only really use it to watch the odd dvd and listen to music with WMP9.
I have a Sony multi-channel receiver/amp with 5. speakers attached.
The amp has multiple digital connections - all either optical or co-axial. (and individual 5. analogue too)
These currently accept optical links from my dvd player and xbox. Lovely.
So, I would prefer to use the digital connections (nice and easy cable approach as with xbox) but I think I'll only get 2 channels when I play dvd... So what is the best way to connect the two....
Thanks
Glen

The thing about that kind of digital connection is that involves compressing 5. channels into the space of 2, using proprietary encodings. This makes sense in terms of storage space savings (i.e. more room on that DVD for special features), or if bandwidth is constrained (i.e. broadcast TV can fit 5. into the space originally designed for stereo), but the only way it makes any kind of sense for getting audio a few feet from the soundcard to a receiver or speaker system is because nothing more direct ends up being available. The result is that your xbox needs a high-powered chip to make something very (and unnecessarily) complex seem simple. Your Audigy does not have that; it does not have the ability to make that kind of 5. audio for your receiver to then decode.
Your Audigy does, in fact, have the ability to output 5. digitally, in the digital space that 6 full-range channels need, using a single cable; but your receiver, like virtually all of such, doesn't accept it. CL digital speaker systems have a "Digital DIN" input which uses it, but your receiver does not have a "Digital DIN" input, nor any equivalent of that. Even if it did, there's still a problem, because it's muted for DVD-Audio's higher-resolution formats, purely as an effort to prevent consumers access to high-resolution digital audio signals that are not encoded, for copy-protection reasons.
Because DVD 5. soundtracks are pre-encoded on the DVD, you don't need the Audigy to be able to encode. All that is needed is to get the soundtrack from the DVD to your receiver as is. The Audigy can do that. As the other post indicates, the keys are to tell the DVD player software to output digital, and to tell the Audigy not to decode.
Under the covers, that actually uses the Audigy as a 2-channel soundcard, and the rest of its channels are "wasted." None of its real multichannel capabilities can actually be used with a "digital" connection like that. However, if all you do is watch DVD's and listen to stereo audio files, especially if your receiver has features to simulate full surround from stereo, you may not care.
Personally, my strong preference is for the multichannel analog hookup, although I might set up both types so I could compare the sound of the receiver's decoding with the Audigy's decoding.
Things you can't do when using an external decoder hookup:
. Use the soundcard to adjust volume while listening to DD/DTS multichannel soundtracks (though it's best to use the receiver to adjust volume all the time, actually).
2. Hear any other sound sources while listening to DD/DTS multichannel soundtracks.
3. Get multichannel audio from PC games.
4. Get multichannel upmixing using CL's CMSS feature.

Simple question re invoking non-WebLogic web services

I have a very simple question that I haven't been able to resolve elsewhere.
I need to invoke 3rd-party SOAP interfaces from my WebLogic 6.1 client EJB. All
the Bea documentation I've found refers to invoking "WebLogic Web Services" and
speaks of downloading the client.jar -- however, in my case it's not a "WebLogic
Web Service" I'm invoking, it's a non-WebLogic web service.
Does WebLogic 6.1's WebServiceProxy (or other tool) allow this? Or must I use
some other SOAP tool such as Apache Axis in this case?
Thanks.
Cheers,
allan

Could this interopability problem have something to do with a problem
I'm experiencing on 61.sp3?
I have an EJB that accesses SOAP services on a Tomcat server. The SOAP
service sends back a SOAP exception which is correct in what I am asking
in to do. However, the weblogic app server is returning a SOAP
exception to my EJB rather than passing the SOAP exception to the API
that I am using to make my SOAP calls.
Has anyone seen something like this?

The 'samples/examples/webservices/rpc/javaClient/XMethodClient'

use that code within your EJB.
The javadocs for the WebServiceProxy class (from BEA's site)
will give you more methods that may be useful to you.
Note that your best bet, if possible, is to use the JAX-RPC
APIs within WebLogic 7. The SOAP support in WL6.1 has
interoperability issues.

Burn underrun protection

I'm trying to burn music CD's, and, as I get 80% done, I get a "The device drained it's buffer without burn underrun protection" prompt. I've successfully burned this playlist before. I suspect a media problem, as the problem started when I started to use a new sleave of discs . I don't have any of the discs from the last batch to check out my theory, but I thought someone out there might know. Any suggestions would be appreciated.
Tom

Tom,
Have you tried using a slower burn speed?

It will cost $49 for a simple question! Not kidding

I called Apple support today with an issue with charging and of course they asked if I wanted to extend my warrenty for another year for $69...when I said not right now the guy then mentioned that after my initial year warrenty was up or the extra year was up, if I were to call in for a simple question they charge $49!!!!!! Don't believe me.....call and ask yourself... how insane is that???? Thank goodness for discussions like this!

ibisguy,
Shh!! I won't tell him. My lips are sealed. He has about 9 years experience working in Call Centers, and has been known to make a mistake or two himself.
However, for the iPhone telephone support is tied to your account with the carrier. In the U.S. that would be AT&T and two years.
The AppleCare Protection Plan extends the hardware coverage to two years. If your iPhone were to break during the second year, any repair except the battery would be $199 (4 GB) or $249 (8 GB) plus shipping, and in some states tax. The battery would be $79 plus $6.95 shipping in the second year. The AppleCare Protection Plan (APP) would cover the battery during that second year if it were to be defective, and shipping for repairs.
This link has more information:

Hope this helps,

This might be a simple question. On those sites that do not differentiate between models when on the internet I.e. Facebook when after your comment and you cannot hit "enter" on an iPad for examp. And speed is slow to connect. What is = to post?

This might be a simple question. On those sites that do not differentiate between CRT, laptop, tablet etc. such as an iPad Mini and using the Facebook site fir example when going to post a comment and you do not have a enter button on the IPad and the speed is slow how do you get your comments to post if we do not have a enter button?

A simple question on random number generation?

Hi,
This is a rather simple question and shows my newbieness quite blatantly!
I'm trying to generate a random number in a part of a test I have.
So, I have a little method which looks like this:
public int getRandomNumber(int number){
        Random random = new Random(number);
        return random.nextInt(number);
    }And in my code I do int random = getRandomNumber(blah)...where blah is always the same number.
My problem is it always returns the same number. What am I missing here. I was under the impression that nextint(int n) was supposed to generate the number randomly!! Obviously I'm doing something wrong or not using the correct thing. Someone please point out my stupidity and point me in the right direction? Ta

I think the idea is that Random will generate the same pseudo-random sequence over and over if you don't supply a seed value. (The better to debug with, my dear.) When you're ready to put an app into production, the seed value should be the current system time in milliseconds to guarantee a new sequence with each run.
Do indeed move Random outside the loop. Think of it like a number factory - instantiate it once and let it pump out the random values for you as needed.

A simple Question about % in CR Chart!

Hi, I have another simple question.
When i use SQL to storage data and wanna Crystal Report to display the data in chart using %
which data type should i use?
float or string?
and I found when i use 0.12 as 12% in database , It could not display in Crystal Report line chart normally.
What should I do??
Please Help!!!
Thank you VERY MUCH!!!

If you have the datatype as string from your database then try adding the string field as a summary field in chart and select maximum instead of count and if you have them in number format then you can directly select the percentage in chart.
