oh right, well from what I know (correct me if I'm wrong), I don't think its
geared up that way, its certainly easier to have a graphics card with TV-out
in each front-end, the front end has the IR receiver etc and potentially
doesn't need a hard disk at all. The backend has your PVR cards and (say) 1
graphics card without TV-out. The PVRs etc write the encoded steams to a
shared/networked disk and all the front ends read it from here, decode it
using myth and display it to your telly via the TV-out. If you're going to
have an IR blaster, it/they would sit on the backend I think, one for each
cable/sat box.

Hope that helps,
Toby
