    I am now having problems playing SD movies across all my applications, they look pixillated. I never had this problem until I updated to 10.6.4. I didn't update iTunes and was/am afraid to do any more updates.

    Anyone else having trouble or does anybody know where I should look for the problem/s?

    iTunes and QuickTime are very interlinked, in that iTunes is just a pretty library software and UI and store for Quicktime in effect - Quicktime is the framework in OS X that iTunes uses to play movies, so it could be that you need to update iTunes and QuickTime before it will play correctly.

    10.6.4 is known to have decreased graphics performance.
