RE: Vista and Quicktime HD (H.264) trailers
I tried uninstalling COREAVC and I'm also running QuickTime Pro 7.1.3 and I
still get very poor performance. My system has an AMD64 3800+ processor with
2 GB RAM and an NVIDIA 6150 graphics chip on the motherboard. This system
worked great with XP Pro. The system requirements must be a higher with Vista
for playback of media files. Just curious, what are your system specs?
