Now, it seems, M$ will only allow HD-DVD and Blu-ray playback in 64 bit Vista because the 32 bit version won't be compliant with copy protection. Oh, and by the way, 64 bit Vista is severely lacking in the full range of necessary drivers for most apps. The concumer, AKA, you 'n me, get the shaftola, once again.
