Not correct with regards to current VM software, the secure path is at the
hardware/ HW driver level and the VM doesn't have access to the hardware
layer of the host at all, it only has emulated devices (S3 Trio and SB16
sound), so it's not DRM capably.  If Vista is in the VM, it knows it has no
secure path and wouldn't play HD.

That's an interesting concept, the VM doesn't have to be Vista even if the
host might be.  If the HD content can be played on the emulated minimal
hardware, it would play, but the performance would be hit or miss.

I don't believe security has anything to do with it, otherwise the whole VM
scenario is not secure for anything.  I've read some interesting
discussions as to what it might really be, and the most plausable is just
the threat of piracy or money.
