itunes video help. Answered

So heres the deal I have an Imac with Mac OS X version 10.4.10 installed a 800 MHz PowerPC G4 256 MB SDRAM. With itunes 7.1.1 installed. now don't get me wrong I love itunes and I couldn't even dream of moving all 80 + GB of music over to another music managing program, but ever since I installed itunes 7.1.1 Ive not been able to play any of the 40 + tv shows and movies that have been downloaded off the itunes store. :(, when you start the video it starts out really jerky and then it freezes then stops, but the sound doesn't skip at all whats happening ?¿? can this be fixed ?¿?


It sounds like something is running in the background using up your processor time. Open the utility "Activity Monitor" located in the Utilities folder in the Applications folder. Then click the title of the 'CPU%' column. This should place whatever program is taking the most CPU time at the top.

If there is a problem activity (task) post it here.

Another thing you might try is to install AppleJack, install it and follow the instructions for cleaning your system.

the CPU usage is normal thats what is confusing me. I will try apple jack and tell you if it works.

Your problem isn't with iTunes, but with Quicktime. Try this.

1) Right-Click (Control-click) one of the problem movies in iTunes, and select, "Show in Finder."

2) Right-Click (Control-click) the movie in Finder, select "Open With... -> Quicktime," and play it there.

3) If the same problem occures, go to http://www.apple.com/quicktime/ and reinstall Quicktime. Launch the new Quicktime and rerun your movie (It will be the first item under "File -> Open Recent." Hopefully, this will have fixed it.

4) If Step 2 worked okay, go to http://www.apple.com/itunes/ and reinstall iTunes.

I know it's a PIA, but you shouldn't be having this kind of problem unless you're running on a 500MHz or less G3...

for me, it only jerks in itunes, not quicklime. somewhere else it said to disable all the direct x options in quick time, and that made the jerking much less noticeable, but it does not jerk in quick time or a different media player

iTunes worked for like a week then it stopped playing vids so I will try the direct x fix and tell you if it works thanks ~Matt

I recommend that you install Flip4Mac and Perian. While DirectX shouldn't be a problem, the above two should handle just about any format of video.

2 things, i have windows, and i want this on my ipod touch that i am getting a little after Christmas.

The iPod isn't going to run DirectX videos at all. They will need to be converted to M4V (MPEG4) in order to run on an iPod Touch. There are a number of video conversion utilities that should work fine in Windows.

they are mostly mp4, but some are mv4. both should work on the ipod

Yes. MP4 video and M4V are actually the same thing. MP4 can also be used for audio only.

so do you have any idea why itunes is showing the same frame every few seconds instead of the one it is supposed to?

Processor Speed too low for the video quality? It's also possible that the video was created with a poorly written compression utility (common with "free" Windows utilities). I would try recompressing the video with Handbreak.

um... i did, and i have a dual core 3.0 ghz processor with 4 gb of ram, so that could not be the problem

Hmmm... And you've tried reinstalling Quicktime and removing/swapping codecs from Quicktime?

what do you mean by "removing/swapping codecs from Quicktime"?

In Windows, Quicktime's codecs are located in a the directory, C:\Program Files\Quicktime\Plugins. The default plugins include 7 npqtplugin DLL files, nsIQTScriptablePlugin.xpt and QuickTimePlugin.class. Any additional files in that folder were added by third-party sources. Temporarily removing additional plugins may help resolve your issues.

Another solution is to completely remove Quicktime and reinstall it. Apple has a step-by-step here.

i completely reinstalled it, and i think that it is fixed. thank you very much


Army intelligence didn't take you out.... Please stay!!

YEY RS - get a forum topic up NOW

I have both these installed ( are you saying to play the vids in flip4mac?)

Flip4Mac is a Quicktime plugin that supports most Windows Media Player files. The "player" is nothing more than a redirector to open WM files with Quicktime when double-clicked.

It worked !!! thank you very much Quicktime was the problem, all my movies work now without any distortion at all. :) ~matt

I installed applejack and did a deep clean and a custom clean and it didn't do any thing for the video problem but it did speed up my login time :)

. I'd try downgrading to whatever version you used to download the files. Assuming that you didn't d/l 80+GB, before trying to fix the problem.

thats what I was going to try first but its really hard to find an older version of itunes, and even if I could I think I would miss cover flow too much :)
