Vista and Quicktime HD (H.264) trailers

Before installing Vista RTM on one of my machines, I was running XP Pro/SP2.
With XP, it would run the HD 1080P movie trailers, which I downloaded from
Apples site, flawlessly. Installing the COREAVC codec helped to get great
performance on picture quality. But now with Vista, even with or without
COREAVC, I cannot get these HD movie trailers to play. Has anyone else had
any success playing these in Vista?

Yes, I've successfully played these HD movie trailers using QT Pro Player
Version 7.1.3 in Vista RTM x64. I do not use the COREAVC codec. Hope this
helps.

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?
