When I play a media file, playback is jumpy especially at the first quarter of the file. I have been to many sites looking for help to fix this problem. AMD 1700+ 1.5GHZ 512 DDR Win XP Pro Direct X 9.0b ATI 8500 w/ 128mb ram I am attempting playback from the hard drive. Any suggestions or help would be appreciated. MY apologies if I missed any references in this forums threads.
