Hi all, tried a 1080i hi def video file the other day and it just about run, a little lag but I feel with a little tweaking will play fine. Anyone know of any guides for optimizing a pc for hi def video playback?
I have a 3gigP4 with 2 gig ram and a nVidia 6800 128ram.

What kind of high def file is it and what program are you using to play it back?
Regards.
