BD?HD-DVD Playback in Windows 7

[DougieB]

Hi
I am running Windows 7 RC Build 7100 (Official Download from MS$)
I have an LG GGC H20L BD/HD-DVD SATA Drive and an upgraded copy of Cyberlink PowerDVD Ultra vers 7.3 (came with the Drive). I am getting lipsync problems on playback on both formats. Anyone know of any fix for this.

PC Homebuilt:
AMD 64x2 7750 BE@3.1Ghz (Akasa AK-875BL Cooler)
Abit A-S78H Mobo
ATI Radeon 4670mj 512Mb DDR3

80Gb Hitachi HDD (Win XP Pro 32Bit)SATA2
LG GGC H20L BD/HD-DVD Drive
