Hello all, started having problems with the playback of movies. Seems to only do it with movies and not the half hour tv shows I watch on it. Video is a little choppy and the audio is out of sync and sometimes cuts in and out and in and out, this is driving me nuts! I am running windows 7 64 bit OS my computer is a
Hp Pavilion A1240n
factory specs -http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00485645&cc=us&dlc=en&lc=en
with an upgrade to a WD black 500gb hard drive and 3x1gb ram sticks instead of the factory 2x512 sticks

Anyone who has ran into this problem please help, it would be much appreciated, Thanks!
