This is really weird...I have a upgraded Pismo (flawless case!) and have OSX 10.4.7 running on it, the OS and all of my programs run fine, I watch dvds and it plays them all the time. Now playing a much smaller (than dvd) video, around 200 megs to 700 megs in Quicktime, DivX, or VLC it is slow as dog poo...any ideas whats causing this and any fix?
