My combined BE/FE is a Pentium dual core, /proc/cpuinfo says it's a Pentium
D 2.66GHZ so I guess the Pentium D and Pentium dual-core are one and the
same. It runs great, I can play back 1080i HD through my HDHomerun (So I
guess that's MPEG-2?) with no issue. I'm using xVMC on an Nvidia PCI-E card.

I built the box myself with parts from Newegg. The reason I went with the
Pentium is because it uses the Socket 775 interface, same as Core 2 Duos and
Core 2 Quads (quad-core CPU). I paid something like $60 for the CPU a year
ago, and when the Core CPUs get around that price, I can just drop a new C2D
or C2Q in and not have to change anything else.

I have not tried H.264 with the system, and prior to VDPAU I was expecting
it to be too slow. Once the magical convergence of VDPAU, HD-PVR and .22
hits the street it will probably need nothing more than a $40 video card,
although now I'm thinking of sticking the box in a closet and getting a
dedicated Atom-based FE. But I'm wildly diverging off-topic :-)
