Toast--Buffer under run protection--does it work?

Lately I have been having trouble with the "device has drained its buffer without under run protection" error. I usually can deal with it with several things I try, but for the last couple of projects I can burn only one or two disks before I start getting this problem. Then I can't burn until I let the computer rest overnight, no matter what I try.
I have heard that Toast has a buffer under run protection option. Does it work? If it does, I'll down load it.

Hi R
Even Toast™ are dependant on the free space on internal hard disk. Even more so
if You use it for capturing material from DVD discs - then to add to the strain
say that it should be changed to fit a new DVD.
Say from a DL-disc to a SL-dito.
Don't be amazed if the need exceeds a 60Gb need.

IDVD6 Buffer under-run through View Image

Higtherto a fair run with iDVD6 but suddenly, no matter what I've tried, when I eventually have run through the creation in iDVD then saved to Image View the complete disc build carries right through to the end then closes with the box message tellingme it has failed through buffer under-run. A waste of approximately 11 hours.
I'm employing OSX.3.9 for the job with my undermentioned spec. The film is a holiiday one of 58 mins 30 secs, and I'm working in PAL with a Pioneer 109 and -R disc.
Maybe I should know what is buffer under-run and maybe it's something I'm doing along the line but I haven't a clue.....
Help required here, people - with thanks.

Apologies - read it as 'when burning from' and confirm that I get as far as having already saved as Disk Image.
I've a number of times gone over the lengthy process of saving from FCP through FCP Movie then iDVD to Disk Image followed by spasmodic print results to disks during this present difficulty. Last night I had one result from Toast 6 and another result from Disk Utility followed by a string of complete failures in the way I have already reported - that fatal "The drive drained its buffer without underrun protection."
I've used Disk Warrior's Optimiser to optimise both my HDs which showed a noticeable difference to the storage graphs. Turned the computer off and on again. Resaved the film in the way described. Gone through the process with Toast and Disk Utillity, and produced one good disk from each. All followiing attempts have ended in failures as described and those attempts have included switching off and on again, not just restarting. My startup disk has 42gb free space and the storage disk containing the edited material has 47gb free space.
So yes - the problem shows from the Disk Image starting point. When I got a result from Toast 6 followed by another one from Disk Utility I thought I'd cracked it. Maybe there's a clue in noting that the failures occurred again after once more using Disk Utility.
Thanks again for your interest.

Buffer Under-run Error

Instaled QT-Pro in my production machine that is not connected to the internet. When starting QT it kind of sticks on the "Loading" screen. If I click on the screen It says "Switching". I can still open a movie though and play it but when I try to export it as anything it gives me a Buffer Under Run error and crashes.
Where should I look? I have reinstaled it and the same file works fine on my other machine.

Finaly figured out my problem after doing some searching. At least with me anyway I had the videos I was working on in the root directory of the drive I was using. Apparently QTP likes them in a folder. Now it all works great.
Let me know if this is your problem too.

Error Buffer Under Run iDVD4

I've downloaded successfully my project in imovie (40mins) and while burning in iDVD, after 4 hours, in the step 4, the following error message came.
"Errors were found during the burning process. The recording device found illegal request. Buffer under run.(0x21, 0x02)"
Only this project I couldn't burn. All the other projects I was able to burn without problem. Appreciate anyone help. Thanks.

[tuner card] cx88 alsa buffer under-run (on xc4000)

I'm having really weird bug and I don't know where should I look for help.
I own Leadtek WinFast DTV2000 H Plus card with Conexant CX2388x PCI bridge and Xcieve XC4000 tuner.
I'm using it with mplayer to watch analog cable tv. I'm suffering from buffer underrun caused by alsa driver (cx88_alsa). What's more interesting it's occurring more often when I'm watching channels only on specific frequencies (mostly high). The side effect of this is that mplayer (also mplayer2) has a memory leak which causes to drop frames after aprox. 10 minutes.
When I'm having underruns dmesg shows something like this:
May 26 11:26:12 localhost kernel: [81922.660861] cx88[0]: irq aud [0x1101] dn_risci1* dnf_of dn_sync*

May 26 11:26:25 localhost kernel: [81935.352440] cx88[0]: irq aud [0x1001] dn_risci1* dn_sync*
I've figured a simple workaround but it's causing sound stuttering on high frequencies (because of more buffer underruns). Disable audio in mplayer and run:
sox -t alsa hw:1,0 -t alsa hw:0,0
I've found similar problem but no one has found a soultion: http://www.digipedia.pl/usenet/thread/17087/5974/
I've tried also applying workaround from https://bugs.launchpad.net/ubuntu/+sour … bug/836062 post #5 but it doesn't work.
I really don't know where should I report this bug. Any help will be really appreciated.

Hi mate,
Just to let you know you are not alone. I have the same issue with Leadtek WinFast DTV2000 H (rev. J) card. It's card=82 on the cx88 driver support list on v4l site.
I'm seeing the same messages on Mythbuntu Lucid 10.04 I just noticed it today troubleshooting some tunning issue. I found some other people having same issue dating from 2007 and 2009 with some other cards too, not sure if the same driver though.

Some of them solved their issue by unloading the cards ALSA driver cx88_alsa but not sure if that is a good idea since that module is used by snd_pcm and will probably have audio impact.

I'm using this card on MythTV setup for watching and recording DVB-T TV and can't say I've noticed any sound issues during playback. But what I've noticed is that the card can't tune some DVB channels here in Australia after I upgraded to MythTV 0.25 and Mythbuntu 10.04.
If you ask me this issue should go to the v4l list since I think is driver related.
Cheers,
Igor

If you check the don't show this again box when closing multiple tabs, how do you get it to warn you when closing multiple tabs, or to save previous tabs? Checking the warn me when closing multiple tabs box under tools/tabs does not work to solve this?

I accidentally checked the do not ask me again box when closing multiple tabs. Now I no longer get a warning when closing multiple tabs, and it saves my previous session. I have tried checking and un-checking the warn me box under tools which has not worked. If I open a second window and try to close multiple tabs it will warn me but not on the first window.

You can reset the warn prefs on the about:config page via the right-click context menu.
browser.tabs.warnOnClose , see http://kb.mozillazine.org/About%3Aconfig_entries
browser.warnOnQuit , see http://kb.mozillazine.org/browser.warnOnQuit

path = "/System/Library/Screen Savers/Cosmos.slideSaver";
type = 4;
showClock = 1;
tokenRemovalAction = 0;
MINE:~ ent$ defaults read com.apple.screensaver {
askForPassword = 1;
askForPasswordDelay = 0;
tokenRemovalAction = 0;
So the settings get applied correctly.
The problem is - after screen saver kicks in or when MacBook goes into sleep mode and I want to continue work - no password prompt appears and I go back to desktop without any authorization!
I see this behaviour on admin user account, but when I login in as root - prompt appears and asks for password to unlock desktop.
Can you help me troubleshoot the problem? How can I log /see what is happeining after screen saver is terminated by mouse move or key stroke?

Krzysztof

Gals, Gents,
I actually figured out the root cause of the problem. I am using EncFS to encrypt my home folder and each time the user logs in a script is being executed:
MINE:~ ent$ cat /Library/Management/loginhook.sh
#!/bin/bash
# $1 = logged in usernam
# try to mount /e using encfs entry in keychain
PASS=$(security find-generic-password -ga EncFS 2>&1 >/dev/null | cut -d'"' -f2)
RAW="/Users/.$1"
MOUNTPOINT="/Users/$1"
echo $PASS | sudo -u $1 /usr/local/bin/encfs -S $RAW $MOUNTPOINT
It is executed as a login hook, so:
MINE:~ ent$ sudo defaults read com.apple.loginwindow
LoginHook = "/Library/Management/loginhook.sh";
LogoutHook = "/Library/Management/logouthook.sh";
The problem with that is that most probably all the Library settings are first read and only after that is the login hook executed. What it actually does is decrypting the EncFS volume and mounting it to the /Users/enc.
So... Library folder get's substituted and I can work on Library preferences files from my account, but they are not visible during the login process.
Anybody know how I can change this process to enable login script before Library is ever read?
I managed to work around with screen saver protection by adding it globally to /Library/Preferences/com.apple.screensaver.plist instead of local ~/Library/Pref..
But obiously that is not how it should be dealt with...
Thanks,
Krzysztof

No longer under warranty, how does pricing work?

Seen as it's impossible to contact Apple directly regarding technical issues regarding MacBook, I'll have to ask here.
Firstly, I know the issues with my MacBook are hardware related I've spent relentless hours trying to fix them with thousands of different software methods, so I don't need any advice with that.
I brought my MacBook in the states, it's an early 2008 issue, so the keyboard and wrist-rest's have all discoloured and the housing is practically falling apart.
One of the RAM slots has failed, so I'm running on a measly 500MB's of RAM, it's not the RAM that has the issue but the slot as I've tested both pieces of RAM in each slot.
The DVD drive no longer burns, it's not a software issue as I've restored the OS, the error I get is the dreaded "Laser power level could not be calibrated for this media" I get this with standard CD-R's now and not just DVD-DL disc's, I've tried the 'language change voodoo' a PRAM reset, disc cleaning with little to no luck, I shouldn't have to do this EVERYTIME I wish to burn a disc.
So basically, I want these three things fixed with the Mac, as I'm no longer under warranty I can understand that I will need to pay. Should I contact the nearest 'Premium Reseller' of Apple products? Will they charge more at the resellers than Apple will? Is it a standard one off payment to fix all three?
Any help at all will be much appreciated.
Thanks.

Seen as it's impossible to contact Apple directly regarding technical issues regarding MacBook
You've called their tech support numbers? (44) 0844 209 0611 in the UK, 800-275-2273 in the US. I've never found them particularly difficult to reach, though depending on call volume you may have to wait on hold for a while. You can also go to any retail Apple Store in your area.
should I contact the nearest 'Premium Reseller' of Apple products? Will they charge more at the resellers than Apple will?
I'd suggest you shop around. There's no standard pricing, so you may find that repair pricing will vary between service centers. Repairs at an Apple Store are more likely to be higher than the price charged by an independent service center, but not always, so get estimates from a couple of places, at least, and decide from there. If you're in the US, you can look for service centers on this web page:
http://www.apple.com/buy/locator/service/
If you have to replace the logic board, the keyboard and the DVD drive, it's almost certainly going to be more cost-effective (and perhaps even less expensive, particularly if you go for a refurbished MacBook) to just buy a new computer.

Mouse Wheel under Windows XP Does not work- 9.0.3

I use Windows XP and JDeveloper9.02 handled mouse wheel scrolling reasonably well(help files could not be scrolled). I can not use the mouse wheel in the Jdeveloper9.03 editor or the help files. Am I missing something? I thought JDeveloper9.03 added mouse wheel capability as its new release feature.
I know user's of windows 98 had problem with mouse wheel. However, migrating to JDeveloper9.03 seems to have fixed the mouse wheel problem for Windows98 users and made it a problem for WindowsXP users!

I work with Ramin. Both he and I just unzipped JDev903 to a new folder (C:\Program Files\OracleJDeveloper903). There was no mention in the readme file about having to uninstall the prior version, and since it didn't have a Windows installer (the files are merely unzipped), we didn't think that it mattered that another version was on disk. He was running only the 903 version -- the 902 version was simply on the disk just like dozens of other programs are on the disk. I don't believe he rebooted after exiting 902 and unzipping 903, if that matters. So I think what he did was
1) run 902
2) quit 902
3) unzip 903 to new folder
4) run 903 and notice mouse doesn't work
Questions: Do you recommend getting rid of 902 totally off your disk? If not, do you recommend installing it to the same folder or a different folder? What about rebooting in-between running/quitting 902 and running 903?
(FYI: By the way, I unzipped it and then tried to open up one of my existing workspaces. I found I couldn't browse up the the root folder. It said "I/O Error: The dir c:\ is not accessible. Please select a different directory." It had me in the c:\Program Files\OracleJDeveloper903 folder and I wanted to go to c:\My Documents. I couldn't browse there because I needed to pass through the root to get there. The workaround was to type in c:\My Documents into the File field. However I'm using Win98 but I plan on going to Win2000. Perhaps that will fix the root problem. My mouse works now in win98 but I hope I don't lose that functionality when I go to 2000.)

Running unidsdiff does not work and I get a "Search Limit Exceeded" error.

When I try to run unidsdiff to correct differences between the Calendar
Server and Directory Server databases, I get an error that the search limit was
exceeded. The strange thing is, unidsdiff works fine on other Calendar machines
in the Calendar node network.

Check to make sure you have an adequate value set for "Size Limit in Entries" on
the Directory Server. This value should be greater than the number of users you
have on the corresponding Calendar Server machine.

For example, if you have 2500 users on the Calendar Server, the Directory Server
setting for "Size Limit in Entries" should be greater than 2500. The default
value is 2000.

FDM Data Protection does not work

Hi experts,
I am trying to implement FDM data protection. Here's the situation: In C4, we have 3 members - LSS, LSSGA, MI. I want to replace only the contents in LSS and preserve the manually entered data in LSSGA and MI members. When I enable data protection with <> "LSS", it works for once. There is a situation here where the data in LSS also gets modified occassionally. Following this, FDM Replace cannot replace the data in member LSS. Has anyone faced this issue before ?
Else, how to enable protection for more than one values ?
Any help is appreciated.
Thanks,
George

You already have an issue from the details you have specified. If you are saving non 'LSS' records, i assume by setting the protection vaue as not equal to 'LSS', then it is going save the 'MI' records, but not the 'LSS' records AND the 'LSSGA' records (It will not save the LSSGA records because it includes the string 'LSS' and that is all the function looks for - it uses the VB Instr function.
To save multiple strings from a single location would involve bespoke changes to the adaptor Export script, or revising your metadatanames so that changing the protection value string could cover multiple dimension names as you have with LSS and LSSGA.

Run-as does not work for servlets

When a servlet is marked with a run-as role, other servlets in the same web app without run-as role will not propagate the caller principal correctly to EJBs.
Is any configuration required except setting the run-as principal in sun-web.xml?

html:link action="" input type="button"... does not work under IE browser

Greeting,
I have the following codes in struts1.3.5. It works fine under Firefox, but it does not work at all under Internet Explore (IT) at all. Any clues why under IE it does not work?
<html:link action="/private/search">
<input
type="button"
value="Search"
class="search-button">
</html:link>
Thanks a lot!

This would probably generate a HTML in which there will be a button inside anchor tag.
This is not a standard HTML feature and no wonder this is not supported by IE. I copied the generated html codes into test.html to try on IE, the button does not work at all.
Firefox is probably lenient here. True. test.html works in Firefox.
You might want to just have a link or do a form submission on button click.The action designed does not need an actionForm. I updated my code to :<html:button onclick="location.href='processSearch'"
property ="Search"
value ="Search">
</html:button>
And now both Firefox & IE works fine.
Thanks a lot!

XP windows restore does not work yet all is set correctly

XP windows restore function does not work. All the restore points exist with descriptions of the changes that prompted them. It will let me select them (restore points) and restore process will strart but after rebooting it will ultimatly let me know that it could not restore.
Does the Lenovo Restore and Rescue utility disable this function of XP ? ?
Thanks

Well I have a 6460-8WU that came with Vista and I got the downgrade CD set and tried to restore to XP. The first time it said it failed to restore my system, but it seem to have XP and all the applications that I expected to see. Later I had a problem with the Welcome Windows screen being unavailable... used only the Classic Windows Logon, I called Microsoft and they suggested using their system restore.... which didn't work at all... I tried 5 or 6 different backup files from different days and none of them worked. At that point I decided to use the Lenovo downgrade CDs and format the hard drive restoring everything from scratch. It took me a few tries but eventually I did get it to say that it had successfully restored my system. The items I learned from like 4 failed attempts to restore it are this:
1. Don't try to restore it while in the advanced dock.
2. When the restore process says to remove Disk # x and press OK, remove Disk # x-1 (the currently inserted Disk, and insert Disk # x, and then do not press OK until you wait 20 or 30 seconds or until the little icon of a CD that flashes when Windows reads a newly inserted disk has finished. When I tried clicking OK either before I had actually inserted the next CD or too soon after I had inserted the next CD the process went downhill from there and failed to restore properly.
3. When it seemingly has read all the CD's and says it will now start the restoration process, but you are asked to press Next... well firstly there *is* no Next button to press and the other buttons other than Cancel are greyed out. The solution there is to wait, and wait, and wait... so long that you may think the process has failed and the computer is hung... but it is not. Eventually it will continue from that point.
Aside from that, I notice that there is a new version of the Recovery Application on the Support site, but
if you install the latest Rescue and Recovery 4.20.0511.00 in the readme there are 31 "considerations" listed, which are basically conditions under which it does not work properly or as expected, so I won't be trusting it to recover my system. I will make a Paragon Drive Manager image after I get the updates all installed and use that to restore from.
