Computer Freezes When Playing Certain DVD

I just bought my first Mac in the form of the new generation of Macbook Pros last week. There is one DVD that seems to always freeze in the same spot when playing in my computer. When I start playing from after that point, it plays normally for awhile and then freezes again. It freezes to the point that I can only shut down the computer to fix it because force quit does not work and I cannot get out of fullscreen mode. I just tried the DVD on a friend's Macbook that he bought in November and it played without any problems. Could this be a problem with the drive or is the DVD probably to blame? Any help would be greatly appreciated, including advice on closing the program without shutting down the computer.

Same problem here. Some notes:
Has occurred on at least two different DVDs for me; both unscratched and playable without issue in other drives.
I believe the picture freezes first, then the sound freezes a few seconds later. Mouse can be moved, but movement is jerky, like the mouse position is being updated at 5fps.
Hard reboot only way out; I've let it sit 20+ minutes to see if it recovers, no luck.

Possible explination of why 5g iPods freeze when playing certain podcasts?

From what I know many of you as with myself are having certain problems playing podcasts on your 5.0/5.5g ipod after updating to firmware 1.2 and iTunes 7.x, I have also read many complaints that this problem mainly exists with CNETS Buzz Out Loud (BOL) podcast. My explanation of this is that some podcasts especially longer podcats (i.e. BOL ) are encoded in a low bit-rate format, and the latest iPod firmware (1.2) has a lot of trouble playing these these low bit-rate podcasts. For now my only answer is to wait until apple acknowledges this problem and releases a new firmware update, which will hopefully come sooner than later. Also I have heard that in some cases turning of the EQ will allow some podcasts to play without crashing the iPod.
Well any way good luck to all of you experiencing problems and hopefully apple will resolve them soon!
Regards--- Justin

I am having the same problem since the upgrade. I don't have a problem with every podcast. I listen to one particular podcast and about 90% of the episodes work. I hope Apple jumps on this problem quickly because it is very frustrating. Please Apple, don't point fingers and accept responsibility for this mistake of yours.

Movies stall or hang up when playing on DVD player

I've used both IDVD 5 and iDVD 6 but the problem continues. DVD's tend to "hang up" or "stick" at multiple scenes when playing on a DVD player. The same problem occurs on all sorts of DVD player of family and friends. This issue does not happen when playing the DVD on a computer. The movies are created in iMovie and the sent to iDVD with Themes added and then burned. I've tried disc immaages vs a burn - same result.
Any ideas what is causing this problem and how to overcome?

My iMac G5 is 2 months old, so probably not an issue. I am currently using Memorex 16X DVD's, but get the stall, hang up and freeze problem when playing on DVD players. This is not an issue playing back on computers. I started making movies on a Dell a year ago using Microsoft Movie Maker and experienced the same problem. Totally different systems, different applications...but the same issue.
All sorts of makes DVD players both in the U.S. and England and Canada have problems playing my DVDs.
I have tried saving as a disc image and the burning, but not a solution.
Is Toast better than using Apple's iDVD or disk utility to burn DVD's. Is there any way to control burn speed? Does Toast allow different burn speeds? Should I use 16X DVD's or 8X or whatever?

Mac Pro Freezes when performing certain Tasks?

My Mac pro has been freezing recently which requires me to hard boot and I'm not quite sure whats going on. Let me go a bit more into detail.
Now when I say freeze, I don't mean beach balling, I mean literally the entire screen is motionless and I must hard reboot. Its odd really, the computer only freezing when doing certain tasks, such as when I render 3D graphics with Cinema4D, or whenever I play certain games on steam.
I have recently installed windows as a partition for bootcamp, but I don't believe that is the issue. I have experienced the freezes while running my machine in both Windows and Mac.
Its important to note that when booting my Mac in SAFEMODE, the freezing does not occur while performing the same tasks. So this leads me to believe there is a process going on thats causing the computer to freeze up?
What I think I have managed to rule out as problems:
- Not a Hard Drive failing issue, I booted from my backup hard drive and the freezing still occurs.
- Not a Heat issue, I've installed iStat and my top temperature barely raises to 60 degrees celsius when freezing occurs.
- Not an issue with the Windows partition, as I booted from my backup drive that is without the partition and the freezes still occur.
- Not a Ram issue, I took my ram cards out and swapped them around.
One other things... Not sure if this is relevant, but upon one of the freezes, I rebooted and got this on my startup screen, It was bizaar and it froze here as well. This only occured once but I snapped a photo of it.
Any ideas? Could it be a graphics card issue?
Thank you for your help!

That panic was not caused by third-party software. If it's a recurring problem, the remaining possibilities are (1) a damaged Mac OS installation; (2) a hardware fault, which could be internal or in a wired peripheral device; and (3) an obscure bug in the Mac OS.
You can rule out the first possibility by reinstalling the Mac OS. Probably there will be no change. In that case, make a "Genius" appointment at an Apple Store to have the machine tested.
Print the first page of the panic report and bring it with you.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros (do this only if you know how to restore, and you have at least two independent backups.) Don’t erase the Lion recovery partition, if present.

Problems playing certain DVDs

Hi.
There seem to be a number of posts with similar issues, but not quite the same.
I've got a PIONEER DVD-RW DVR-107D which has recently begun to have issues playing certain DVDs. It seems selective in it's decision to mount them - playing some, not playing others.... Sometimes, I insert it a second time and it will work, but generally - if it won't show up the first time, it ain't happening.
When they don't work, it makes a horrible grumbling noise before spitting them out.
I can't seem to figure out why some work and others don't....... They're all bought DVDs - nothing burnt or iffy. DVDs that have even worked in the past.
Does anyone have any ideas?
Thanks and I am sorry if this is somewhat reminiscent of other posts.

Hi discarnatequern-
Greetings and welcome to the Apple boards
It sounds like the drive is,about to fail completely. Have you tried a lens-cleaning kit? Some folks have reported success in cleaning the drive.

DVD drive plays certain dvds and others not

I've accidently locked my dvd drive to a certain region (not sure which), and i know that i cant unlock it. But i realise that i can play certain dvds and others not, for example in my Will & Grace collection i can play the first 5 seasons but not the later ones. When i try to play the later ones, dvd player tells me to eject it because 'the dvd does not match the drive region code'...But why can i play the other ones which have the same region code??

If you locked your machine in the wrong region code, take it in for service.

No sound when playing burned DVD with Windows Media Player

Hello!
I made a 10 minute movie which I burned , tested and delivered today.
But it turns out that when playing the DVD with WMP, there is no sound.
I had tested the movie playing it with powerDVD, and it worked as it should. When playing it with a normal DVD player and TV it works allright.
But I had not tested it with WMP. And sure enough, when playing it with WMP there is no sound!
The ones who will show the DVD will do it from a computer to a video projector, and maybe they don't have a "proper" DVD program installed. But I heard that there was sound when playing with "VLC" which is a relief.
But I feel the need to get to the bottom of why there is no sound with WMP? Any clues?

In NTSC-land, one has but two choices: PCM/WAV or DD AC3, which is a particular "flavor" of MPEG. In PAL-land, one does have the option of MPEG (not DD AC3) as an option, but that seems to be falling out of favor.
When MS was re-tooling WMP, they wanted to add back the functionality of commercial (pressed/replicated) DVD's, but sought to limit any burned DVD's. Do not know what the mindset is now, so much could have changed with a few iterations of WMP. I have to admit that I just do not reach for it that often.
In the Project, or Disc, menus, one can tell En which Audio Transcoding to use. As John T, suggests, I would definitely do a test with PCM/WAV, and X my fingers.
If your client(s) is/are set on WMP as the player, there is hopefully a scheme that you can get to work. Also, remember that some older versions of WMP might not play the DVD at all, unless one finds the right plug-in, that basically hacked the intended setup in those older versions. Just like when delivering to a client, and not knowing their systems' calibration, or setup, trying to cover every base in a particular player software might involve a lot of work, and prayer.
Good luck,
Hunt

No sound when playing a DVD on my Lenovo 3000 N200 (0769-A44)

Hi,
I recently got an N200 under Vista Home Premium. Everything is doing well, except an annoying problem with PowerDVD 7 which is factory-installed. When I play a DVD with PowerDVD, there is no sound. With Windows Media player, MediaCenter and even MediaPlayer Classic, the sound is there. Only with PowerDVD is there no sound.
Any hint on how to solve this ?
Thanks !
.merle1.
Update 2008-04-30 : the problem only appears when playing commercial DVD that rely on AC3 codec for sound. For recorded DVD that use MPEG2-Layer2, sound is OK. Seems to be a limitation of PowerDVD OEM. However, if there is a solution ...

Thanks for sharing this. For the moment, and until someone finds a solution, I am relying on WMP and also on an opensource player that can play DVD, Media Player Classic :

Very easy to use. May be it will solve your problem with the DVD player noise ? There is also an excellent media play, that plays DVD, and that I intend to install : JetAudio 7, from Cowon.

Computer lags when playing games.

Hi folks.
I have a problem with my computer, several in fact.
1. Computer lags when playing games(Battlefield/Desert Combat) even on lowest video settings, especially when there is a lot of action.
2. When I open "My Computer" it searches for 3-5 minutes before files appear, but when opening "my documents" for example, it opens it without any delay.
3. Startup is fast but when logging on, computer hangs for a couple of minutes, before completing log on.
Is there anyone who can help me out???
plz help

Hi NovJoe, thanks for the reply. Nice rig by the way.
Ive disabled all programs except essential windows programs in Task Manager, it didnt help.
Ive changed to new drivers, uninstalled them, changed to older drivers, tried 7 different drivers.
VGA card is running cold, CPU is on 40 cel. under full load, RAM is cool as well. PSU isnt running hot either.
Even checked the chipset, and thats cool also. I switched cabinets and that helped a bit(different PSU).
Now I only have problems with the lagging when playing.
So now Ive ordered a new PSU and mobo (MSI 865PE NEO2-V) I have a feeling its the VGA slot thats not giving me enough power to the VGA card.
And the new PSU is just so cool I had to have it. When Ive complete the build Ill post pics on the forum.
Anyways, Ill let you guys know if this will solve my problem.

I have a 5th gen ipod nano that freezes when playing songs. i can't turn off, change songs, turn volume down. song stays stuck and nothing works at all. any ideas??

You have 2 options: #1 - iPod Repair Tutorials
#2 - take the iPod Nano to an Apple store or an AASP. Whichever is more convenient for you.

ITunes and Computer freezes when ipod is connected

When I connect my video ipod to my computer (dell desktop) the system freezes, as in it will not respond to mouse clicks and keyboard (but can still get to task manager). When I unplug the ipod it comes back to life. Programs always freeze, but sometimes I am able to navigate within windows without it freezing, but as soon as a program is brought up, my computer falls to its knees.
I have the latest version of iTunes, and updater v. 1.1, (but I have not been able to update the firmware yet from v 1.0).
The odd thing is last night I was able to download several gigs worth of music to it without incident. I then tried to load movies (they were in the wrong format, but I didn't know it at the time), and so in an effort to correct that I uninstalled itunes, the ipod drivers, and the ipod updater programs several times.
I cannot update the ipod firmware because the computer freezes when the ipod is plugged in, so the program freezes as well. Kind of a catch 22 situation.
I have been over the forums and help archives for about an hour and a half now and I have come up dry.
Windows XP does recognize the ipod when the cable is connected, and the ipod flashes, "Do not disconnect", which it is supposed to do.
I suspect this is drivers/software, but I have no idea where to go from here.
Help?

Hey!
That EXACT thing happened to me! 2 nights ago I'm downloading like crazy, all is well. I got on LimeWire and downloaded some videos and tried to put them on my iPod. Imported them into iTunes then tried to put em on my iPod and it completely wiped out all my songs! So I get back on, put the songs back in, and about half way through the update the thing freezes. I've re-installed everything, and have reset my iPod. Did you figure out what to do? Maybe your fix will fix my problem, too.
Thank you!

Message by mpv and ffplay when playing certain flac files

When playing certain flac files with mpv or ffplay, I experience colored messages which might be warnings or errors in the terminal. I don't hear that something is wrong with the audio and therefore I ignored it for a long time. But I'm a bit curious why this message occures because the files are converted from CDs with the flac tool itself. The output I am talking about looks like this (in orange) when playing with mpv:
[ffmpeg] NULL: sample/frame number mismatch in adjacent frames
And it looks like this when playing with ffplay (in cyan and orange):
[flac @ 0x7f73e0001760] sample/frame number mismatch in adjacent frames
When decoding with the flac utility, I don't see any messages. Does anybody know, where this behavior comes from? Might it be a good idea to rip and reencode the audio again or can I safely ignore these messages?

Thanks for your answer!

Yes, they are the vanilla packages from the repos.
karol wrote:Have you tried playing these files on another, non-Arch, system?
Well, I just updated an old Gentoo (which took some time) and experience the same messages with these files. Interestingly, when I fastforward, the message does not appear (on both systems).
karol wrote:Google shows these messages are pretty common, but since nothing seems to be broken, I don't think you need to worry.
Yes, I also tried to search these messages on Google. But I did not understand most of it. It's just that I could not understand why a file that was encoded by flac itself produce errors/warnings or anything like that when playing and just make sure that nothing is broken.

Why does my video suddenly freeze when playing ?

why does my video suddenly freeze when playing ?

Which app are you using to play the videos? Which version?
Are these offline or browser videos? Both?
Videos flash based?

Why does my computer freeze when updateing if i have enough disk space and no disk repairs are needed?

I have problems updating my softwarebecause my computer freezes when it restarts to install. I have enough disk space and I checked for disk repairs and everthing is ok. Still can't update and not my cumputer is taking longer to turn on. There is an earth blinking then i get the apple logo blinking before it turns on and this takes close to 5 minutes.

When you say, "disk repairs" are you referiring to permissions or verifying the disk because clearly there's a problem.
Boot from your install disc, run Disk Utilty to "verify" and if necessary repair the startup disk. (Not Verify Disk Permissions).
Using Disk Utility to verify or repair disks
