This is a new build with hardware I have around. My primary reason for this 
is to get HD-PVR support from the 0.22 version. Other than that the older 
B/E (0.20) is doing everything I need it to do.

I figure it's easier to build a new machine than to upgrade an existing one, 
and it won't require taking the old one out of service until the new one can 
take over.

Then I plan to set up my newly-acquired Revo as another F/E, probably 
netboot it.

In the past the 64-bit versions of the nVidia drivers tended to be 
problematical, but I hope that's behind us. I want the new B/E to also have a 
F/E in it, I have a GT-220 card to use for that, so I will have VDPAU on both 
F/Es (GT-220 and ION).
