iTunes 10.5 Video Choppiness
Hi Folks. New here. I like it.
I've got a brand new Dell PC XPS 9100. The basic specs are below, but it's configured direct from Dell, so I'm not aware of the brand of RAM, who made the mobo, etc.
What I do know is that the machine runs flawlessly except for one annoying problem. iTunes video, whether purchased or my own, will have brief but noticeable choppiness. Sometimes, it will pause for a second or two, and be choppy, like it's skipping frames. Audio is unaffected and there are no audio/video sync problems and no crashes.
Strangely, other times it's completely smooth. Even during the same video it will be smooth, and not smooth.
Even more strange, moving the mouse around and causing the OSD to appear on screen actually smooths it out.
This began the day I got the PC with iTunes 10.4.1. The 10.5 upgrade after a reformat has not helped. The video did NOT do this on Quicktime or WMP, however, with protected files, you can now ONLY play them in iTunes. QT won't play them anymore now that iTunes 10.5 doesn't require it. So that option is out.
What I have tried so far...
*Uninstalling and reinstalling iTunes and QT
*Updating all video drivers
*Disabling DirectX use in QT prefs
*Disabling the sound card temporarily (read somewhere this might help)
*Reformatting and reinstalling Windows from factory state.
That's what I've done. Can anyone offer any other ideas?
Mainly, it's the TV shows I've bought from iTunes that I am concerned about. I HAVE to use iTunes to view those.
Anything else, I'm happy to just use other software if needed.
Thanks.
