I am experimenting same. Vista Ultimate runs all great until I tried to watch a video (made with Photos Story 3) and listen to music (that I have ripped to my drive). I am trying to determine if it is the drivers that are not yet optimized or is it just that a P4 2.8Ghz HT is not good enough so that I can give it up on this system. I do not have answers yet. Here are my comp. specs.
P4 2.8Ghz HT Prescott
Asus P4P-VM MOBO (800 FSB)
3Gb Dual Channels DDR PC3200
ATI X1650 PRO (AGP) 512Mb
120Gb SATA-150
I recently upgraded to Vista Home Premium and have had few problems. The OS and other programs run great, but when I try to watch a video it playes in slow motion. This is regarless of file type or program used. Any help would be appreciated.
