ITunes video playback lags badly ever since 10.3.6

I am now running 10.3.7 and iTunes 10.5.3 on a 2011 MacBook Pro (2.2 GHz, i7. 8GB RAM) and video always stutters or lags in iTunes, even without any other applications open and offline. I have tried zapping pram and the usual tactics for things like this, and hoped the update to 10.3.7 would solve it but no luck. Help?

Just updated iTunes to most recent version. Now I'm getting jerky video playback in BOTH iTunes and QT Pro (latest version). CPU use is very high but random; ditto with video playback (i.e., doesn't hang up on the same scene/time).
I had this issue a little over a year ago after updating iTunes to the then latest version. Got nowhere with Apple's "Service" texts. I played around with configs for a while and also re-installed iTunes. It has worked fine until yesterday (same symptoms as last time). As for the past "fix": nothing I can hang a hat on. Methinks Apple updated the version I re-installed with (tho' the version # was unchanged).

G5 crashes during iTunes video playback after Leopard install

I have a G5 1.6 single-processor running 10.5.1. Since I installed Leopard, I have been experiences frequent crashes during iTunes video playback (TV shows bought in the iTunes store). The crashes hang my whole system and require a restart by holding down the power button. The video itself sort of "blip-blip-blips" during the crash, but the mouse and keyboard are unresponsive, windows don't do anything, etc.
Any thoughts? Anyone else with this problem? Thanks!

Ever since I installed Leopard on my dual 2ghz G5, neither itunes nor quicktime player works. They both crash on launch. Maybe not the same issue, but I'm regretting the upgrade.

Problem with itunes video playback.

many of my high quality video files seem to run so smoothly with my media players lik VLC, but when i play them in itunes the video gets stuck and the audio keeps playing.. how do i solve this..

What was the fix for this? Everything has sucked for my itunes video playback since the last major revision release.

Auto-upgraded to itunes 6.0.5 - crashes ever since

I auto-upgraded to itunes 6.0.5 - crashes ever since. I have - corrected preferences, restarted, closed all other programs, restarted.
Tried to re-install itunes with fresh copy downloaded from your site.
On re-installation dialogue box says the three packages have been disabled.
Got rid of all iTune prefs I could find, tried again, same thing.
SO: I can't use Itunes, i cant re-install ITunes.
PLEASE, someone tell me what to do!

Remove the 'iTunesX.pkg' and (if present) the 'iTunesX 6.0.4' files from ./Library/Receipts.
That should at least enable you to re-install iTunes.
If iTunes keeps crashing, it might help to re-run the latest combo-update for Mac OS X 10.3.
Sometimes it can fix these kind of problems.
Hope this helps.

Faulty iTunes Video Playback

Dear All,
I’ve unfortunately encountered a problem with iTunes video playback after installing iTunes 10 (and now iTunes 10.1) on my new Dell computer. The computer has hardware which should run iTunes with no problems (dedicated video card, 4 GB ram and a nice screen), and has Windows 7 installed, with the newest BOIS (Dell Studio XPS 16).
My iTunes video though is faulty. TV Shows bought from iTunes run in a way that’s halting and really choppy. No other video plays this way on the computer, just in iTunes. And its much more exaggerated when the video is stretched to full screen or made larger in any way. Its unnoticeable if I make the video the size of a notecard on my computer. It makes video unwatchable if its full screen.
Anything I can do? Any ideas? I’ve followed all the suggestions in this article to no avail (http://support.apple.com/kb/TS1718), except for the IDE step, which doesn’t seem to be an option on my computer?
Thank you for all your help.

There have been reports of problems like this when iTunes has a big version jump.
I've not witness any problems that you have, I'm running on low power on battery and video still plays fine in iTunes, even fullscreen. My laptop is probably less powerful than yours is.
Problems like this seem to come about if there is a major software revision and the software isn't removed properly before installing a newer version.
Try http://support.apple.com/kb/HT1923 this is how to completely remove iTunes to install a newer version. Best to do a backup first just in case. If that doesn't work, there is another way, but we'll try that one for now.

Are you having iTunes video playback problems?

Do you have iTunes Store-bought videos whose playback is terrible, all choppy and full of freezes while playing back in iTunes?
Have you copied one of those iTunes videos to a thumb drive and had it play back perfectly?
This problem is not fixed by any of the Quicktime adjustments that Apple suggests on their "how to fix video playback issues" page, and, aside from this video playback issue, iTunes is working fine on my machine. As I said, the videos work fine, too, if played from a thumb drive instead of the hard drive.
This has been going on for weeks, and people have been posting about it here on the forum, but, to my knowledge, there's no fix. Just silence.
It might be useful if people who are seeing this problem post some information about their systems. For all I know, all of us who are seeing this problem have one particular vendor's computer.
The computer I am having this problem with is a new HP laptop that came with Vista. This one:

2 X 512KB L2 Cache
2048MB DDR2 System Memory (2 Dimm)
NVIDIA GeForce Go 6150 (UMA)
120GB 5400RPM (SATA)
I think the problem has to do with SATA, but I don't really know, except that my computer has it and I am able to play these videos perfectly from a thumb drive but not the SATA hard drive.
If you are having this problem, please consider posting your computer's info. Thanks.
HP Pavilion Entertainment PC Other OS Vista

OK, I figured it out... I too have a dv6000 with Vista and I have been trying to fix this terrible itunes video playback thing and this is what I found. For whatever reason the NVidia driver in the dv series doesn't play nice with Vista. They say that they are looking into it but have no response other than that. Somehow the data from the hard drive isn't fast enough. So, reading this I figured that if that REALLY is the problem that I could use a external drive and have the videos come from there, and Voila!! It works like a charm, no skipping, no stalling, no more blue screens. I hope this is helpful, I know what a pain this can be.
ALSO, apparently some think that you can't watch itunes video while using Vista's "ReadyBoost". I haven't had that issue personally, but I have seen a lot that have who disabled it and had it work fine.
Let me know if this works for everyone else.

ITunes Video Playback Choppy/Laggy?

I am running a 27" 2011 iMac, 3.4 GHz Intel Core i7, 8 GB RAM and AMD Radeon HD 6970M 1025 MB graphics card. I am running the newest editon of Mountain Lion.
This is the first time I have had this, however I am not impressed at all. Video playback becomes laggy/choppy, the sound goes all fuzzy and becomes out of sync. It first started with "Blue Planet", I got it about 3 weeks ago now and I simply cannot finish the series as the play back becomes horrible. I have "Ancient Aliens" and that never done anything like that on the same machine. Even the HD version played perfectly.
Now I have just rented "The Hunger Games" in HD and I'm getting the same **** thing. When I pause the video for a little it stops, then it comes back again. Like watching a video with bad internet connection on YouTube, only it doesn't freeze, it just lags out.
I don't really fancy sitting through a 2 hour film pausing it every 15 mins, if I wanted to do that I'd have just not paid for it.
When I looked at my iStat Menu's CPU and RAM is not being used to much so it's not that. It shouldn't be anything to do with my internet connection, that was the whole point of downloading it? Plus my internet is 60MB (so 6MB/s) and I downloaded the 4.5GB file in 30 mins or so. So even if my internet connection had anything to do with it, it should be fine.
Like I said I've not had problems with this before, but this is stupid. Can this be fixed? If not I need to try and get a refund as this is a joke.

Thanks for your reply.
Ugh. Sorry. It is frustrating and in today's technological marketplace should be one of the easier things for the Mac to handle.
Received another feedback from someone. Have to try when my daughter gets up, but right-clicking on iTunes and doing a Get Info will yield the 'Run in 32bit mode', Checking this box helped another person who was floggedw with this issue
The whole thing is odd. The Choppy playback was an issue oh her machine prior to upgrading to iTunes 11 and me adding another 4GB of RAM. Ran disk utility, did all the normal things to try and solve. She doesn't have an i-device, so WIFI sync was a moot point.
I do not have the issue on my MBPro 15" running the same compliment of software and iTunes. Same movie plays fine. On hers, the issue is there. So this has to be software... settings, conflict, something...
UPDATE
Just tried the 32bit mode on her machine and same choppy results. Back to square zero.

SEVERE, MAJOR Problems with ITunes Video Playback on 64-bit Win7

So I got a new rig (ASUS G74SX running 64-bit Win7 Home Prem) after I figured my nearly 5-year old HP Pav dv9500t running 32-bit Vista Home Prem had put in good years of work. In using ITunes on the Vista system, I never really saw problems with its player on video podcasts.
Completely different story on the Win7 machine. Aside from all the other problems noted with ITunes itself (not the player) in this forum, there is this:
1. When something like UAC occurs, the video clip runs in the player, but the video is frozen (like a photographic still) while the audio continues to run on normally. Workaround: minimize then restore the player window, then the video part of playback returns. Of course that gets annoying doing that multiple times after a while.
2. With one video podcast (for example, The Young Turks podcasts), while the audio again continues normally, the video track lags unbelievably. The video appears in slow motion. The viewer risks a headache from vertigo if the viewer continues watching slow motion video unmatched with the normal audio.
At first I considered the possiblity that it was related to a 5400 rpm hard disk drive, which came with the new machine and I would not have normally have not bought myself, but I had someone buying it for me (my HP system only had 7200 rpm drives...what is ASUS thinking in letting Best Buy do a performance markdown?). Then I played that video podcast with VLC media player, and it absolutely had NO problem keeping up with the video and audio. (Another thing to like and prefer with this player is that you can keep the window on top.)
Seriously, the programming group at ITunes should be ashamed and maybe every member of its group should consider getting another day job. With each revision, ITunes seems to get worse.

My installation of version 10.6.x of ITunes does not have QuickTime.
As of version 10.5 of ITunes, QuickTime is no longer apparently bundled with ITunes, which clearly has its own player. In addition, I have used a minimal install of ITunes. This eliminates the install of the bug-ridden Bonjour service, which was filling up Windows event logs needlessly and crashing from time to time anyway.
Now although I installed ITunes only a few days ago in this new laptop, I did find ITunes in the Programs & Features page and clicked Repair. After the "repair," I played the video revealing the flaws of the ITunes player, and the playback problems were still there. I used the other media player and it played flawlessly.

ITunes video playback stutter

Hello all, when I play a movie in fullscreen mode in iTunes on my 2011 iMac the playback stutters every four or five seconds, this only occurs in fullscreen mode, has anyone heard of this and are there any solutions, it's driving me crazy, thanks in advance

I am having this same problem. Again I have a 2011 27" iMac running Lion. The stutter or frame rate lag is only happening with iTunes videos when being watched in full screen mode. However, it does not happen with every itunes video - only some. Yet they can be HD, normal quality, rental or not rental - it is strange that there seems no reason why one video would stutter while another would not. The lag occurs particularly when the shots are panning or moveing quickly. I have not found a solution yet. Could be a Lion problem i suspect as I did not have this issue with snow leopard. Any one else got this issue?

ITunes Video Playback - Sound skipping

Hi - Just bought a new PC and have installed iTunes and brought over all my sound and video files to it via iPod hard disk function. Music is playing perfectly. All video playback is accompanied by terrible stuttering and spluttering of the audio. This is occuring at all times - even if iTunes is the only app running. DVD playback fantastic on PC as is video playback using other apps. Videos i'm trying to play are all under 5 minutes long and differ in type from video podcasts to Pixar content bought from itunes shop. New PC has brilliant spec so don't understand - any suggestions? All help much appreciated - regards!!

I almost have the same problem with the Video Podcast the sound is bad, For the audio only it works perfectly. At first everything was in order and worked well.
Then for no reason I got the trouble with the sound of the Video Podcast there was echoes and the quality was poor.
Cause it’s new computer I re-installed everything, so it worked well again. Then after going on a web site that uses active X for animation I got the problem back. I have no idea if Active X QuickTime are connected but each time the pattern the same.
Have tried to re-install iTunes the Quick Time I have changed the Audio option about filters in both nothing helped.

How do I stop my itunes video playback from skipping

WINDOWS VISTA ITUNES VIDEO PLAYBACK ISSUE!!!!!! AAHHHHHHH!!! HELP!!!!!!!!!!

am using a Dell XPS GEN 5 PC with Windows Vista Premium Edition as the current OS installed. I have latested up date for Itunes and QuickTime (7.1.6) Installed. I have recently bought and downloaded 3 of the Original Star Trek Tv Shows from Itunes. When I try and play one of them, they don't work. The Screen comes up, the show starts, then stops. Sometimes the sound keeps on playing, and then stops. Sometimes it just dosent even come on. I'm guessing (as a highly advanced Windows PC User) That this ia a "video/playback issue, related to a Apple/Vista Compatibility problem. I would like help solving this problem.

hi slideaway!
my computer has a right proper meltdown, switching itself off and restarting to a "Windows has recovered from a serious error" sort of message.
good lord. are you getting any sort of blue screen? if so, what numerical and text codes are you getting with it? (ie 0x[zeros/letters/numbers] CAPSANDUNDERSCORES)
here's a reference on the sorts of things i'm asking about:
Troubleshooting Windows Stop Messages
if you're not seeing a blue screen (or just a flash of one), we can use this technique to make hidden blue screens appear for us:
1) Open your system control panel (Start->Control Panels->System).
2) Select the "Advanced" tab.
3) Click the "Startup and Recover" section's "Settings" button
4) Verify that under "System Failure" the "Automatically restart" checkbox is not checked.

Video playback lagging while buffering

Having a problem with video in my iPad app. The video is loaded from a server into an FLVPlayback component. While the video is buffering, the video playback is extremely choppy (like 1-2 FPS), but as soon as the buffering is complete, it plays smoothly. So obviously, the buffering itself uses too many resources (I've tested both on an iPad Mini and an ancient iPad 1).
Is there any way to reduce the resource usage of the buffering process so I can start playing before buffering is complete? YouTube is able to buffer while playing the same devices, so it should be possible. The videos are pretty low quality and around 70mb, and the bufferTime is default, not that that should make a difference.

But that's not the problem. The problem is that I cannot play the video smoothly while buffering is going on. It doesn't matter how much has actually buffered. It's as if the iPad's CPU is too bogged down by the buffering to play video at the same time, but I don't understand why, since YouTube and other apps (not made by me) are obviously able to do it on the same iPads.

ITunes video playback quality is not that smooth

Hello:
Two questions--
1. Why do the music videos I purchase on iTunes (and then play on iTunes) freeze up for a few seconds after I push play, but then otherwise playback is OK?
2. Why does the "spinning beachball" appear almost everytime I press play for a video?
Comment--
Given that my Mac more than meets the minimum system requirements for video playback, I think the videos should play smoothly from start to finish, especially at $1.99 a piece. I suspect that the playback bugs listed above are the result of iTunes not being that good/powerful of a video player. Hopefully, these issues will be resolved upon future iTunes software updates. In the meantime, I will not purchase anymore videos.
Thanks.

How do I get a picture in my iTunes video playback screen?
