iTunes 10.5 Video Choppiness

It almost sounds like your PC is trying to sleep or the monitor, when you move the mouse it quits. What are your settings for sleep on monitor, PC and hard disk?

PC set to never sleep - monitor turn off after one hour, no screen saver.
The behavior is as follows. Play an iTunes video, go to full screen, the OSD with the skip and volume/closed captioning controls disappears, and eventually, sometimes right away, the choppy missed-frame-looking behavior begins, especially noticeable on camera pans and zooms.
Wiggle the mouse, make the OSD re-appear, and things look smooth, save for the cursor moving around on the screen. Stop, the OSD disappears, and the choppiness resumes.
It's important to point out, it does not ALWAYS do this, but does so most of the time. Every once in a while I can get thru 10-15 min of video with no choppiness. Even then, it sometimes goes away for a while.
Reducing from full-screen does not help.
More info than you bargained for, but I'm becoming more and more convinced iTunes 10 is the issue. Before 10.5, you could use Quicktime to play purchased TV shows, and it did NOT exhibit this behavior. Now, these iTunes-bought videos will ONLY play in iTunes itself.
I'm gonna try the HDMI cable and see, but I may have to downgrade to an old version, just live with it, or simply limit my viewing of these shows to my iPad only.

OK, I got the HDMI cable and that didn't work either. However my assumption about QuickTime not playing these files was wrong. It WOULDN'T play them before but the install must have been bad.
So, I will just play them in QT 7 and move on with life.
Thank you for the help!

That bites. Is everything on one disk? I have iTunes on the OS disk, but my iTunes folder is on a separate disk. If your library isn't to big, might try moving that folder to another drive and point iTunes to where it's at. Could be the disk not able to keep up but kind of doubt it. Do you know the cache size of the disk? Something is causing iTunes to choke. Just need to figure out where. I'll get back to you after I check out a few things.

Cache size is 32MB. Pretty modern drive, so I kinda doubt it. No other software gives me issues, including QuickTime playing the exact same files.
I've heard rumors that iTunes x64 really is 32-bit? Don't know if that's true, or if that makes a diff.
I've also tried playing a file off a flash drive in iTunes and the behavior was still there.
I appreciate the time.

Was looking at processes today and saw iTunes with a asterisk 32 associated with it while checking the settings. Will be emailing apple about this to see what they say. Am a bit stumped on your issue. Have you tried apple's forum to see if someone has an answer?

Was just looking on apple support forum. Don't update to 10.5 from what I have read. Looks like allot of issues. BTW, in iTunes, are you logged in on your iTunes account when using iTunes? Just a shot in the dark.

I have the same issue on my laptop. Windows 7 64-bit (Core i3 processor).
I'm getting ready to try an old version of iTunes (8.1 or so, when 64-bit iTunes was first introduced) to see if it solves the problem.
Edit:
K, apparently something in the old iTunes installation is pulling a newer file from the web and it cannot read the file because it was created for/in a newer version of iTunes. So.... I guess I can't run iTunes 8.1('ish). Maybe I'll try a bit of a newer version...
Edit 2:
Ahhh, all I had to do was trash the old ("newer") library file that was sitting in the iTunes music folder.
Running iTunes 10.2.1 (64-bit) and trying all DirectX options for QuickTime settings. Still choppy. ARGHHHH.
