mcdermotx said:You could try and use the VLC player with QT h.264 1080p files..
Much better performance than with the standard QT player..
Playback is nice and smooth.......but I find the 1080p files still suck due to the artefacting and 'haloing' in the image.......720p is a little better..
QT H.264 still needs a bit of work......WMVHD 1080p of the Batman Begins trailer was very impressive in comparison
try coreavc. makes 1080i h264 just about playable on a 2500+ aXP

miles better than ffdshows decoder
