Sluggish/jerky video...
I have a G4 laptop (500megahertz/ 768 megs RAM) and a G5 dual 2.7 (2.5 gigs RAM.) I have bought 3 TV shows and 1 movie through itunes and the playback on both of these computers is too sluggish and jerky to watch them. Podcasts run great. I view tv shows, movie, and podcasts using itunes. I am running 10.3.9 on the laptop and 10.4.x on the G5 dual. I have the most recent version of itunes on both computers.
I have run Onyx on both computers but the problem still exists. Any suggestions?
Thanks...

Same problem in quicktime...wonder what it could be?
Ah in that case I would do the usual maintainence first. I'm not sure what Onyx does again but I think the normal tasks are for the usual script running. If it has a cache cleaning tool, you can use it but I use cocktail ( http://www.maintain.se/cocktail/index.php ). In the files section in that program, choose to clean your kernel and user caches and include all the option inside those. Reboot after you do this (the new version asks you to anyway). The reboot will take longer as it's rebuilding.
Do a permissions repair too using Disk Utility.
Check to see if you have any odd quicktime components installed in /Library/Quicktime or the users equivalent.
You can also check your audio settings in the /Applications/Utilities/Audio Midi Setup. It's a bit of an obscure place to put it but I've heard of the settings in there messing up quicktime playback because the audio rate is too high.
I presume that you have tried just restarting your machine? That actually sorts out some Quicktime glitches on its own. It's a system-level component so just restarting quicktime itself doesn't sort it out.
I have no idea what your problem might be, but the machines are definitely capable of the task.
Not sure why both of my computers (G4 laptop and G5 dual 2.7) have the same problem playing back itune movies/tv shows. Symptoms are the same...jerky/sluggish playback. It gets worse as the movie goes on...unwatchable.
They will show a lot of artifacts on a big screen, as they were ripped at an iPod resolution, but playback should still be silky smooth.
Try playing them using VLC ?... same problem ? (though perhaps that won't work if they are DRM'd)
Create a new account.
Copy movies to a place where the 'new account' can see them... (shared folder?)
Login as 'new account'
Play movies
If the slow-down is system wide this should tell you...

(On my G5 I downloaded a movie from itunes a while back and it has always done a freeze frame kind of thing every 10 sec. or so. I have my G5 optimized for rercording music ((Digital Performer. ProTools, etc.)) so nothing is running in the background...just internet service for updating software.)
Funny thing is I got a receipt today from itunes of the particular download in question. It was a $1.99 purchase. They had charged me $0.00. Could there have been an error while downloading...and itunes decided not to charge me? You think they would have let me know if it was a faulty download. Weird!
Anyhow, still trying to figure it out. I will try you guy's suggestions with different viewers and such and let you know if that works.
If you think of anything else to try please let me know.
Thanks again,

I will create a new itunes account and see if that is the problem.
He meant a new system user account.

Where are you downloading from? It could well be corrupted downloads if it only happens with itunes downloads.
