There have been serious problems with Video, and even the desktop display, right from the beginning. DVD and other video's stored on or played locally on my P.C. dont play at all well. Video track freezes and skips constantly at first, then just totally locks up. Oddly enough the sound track continues to play when this happens. flash videos embedded in webpages play fine. ( which kind of sux since those are mostly ads.) Online streaming divx or mov videos dont play at all.
Some games wont run because the video sequences crash.
