I'd been laboring under the impression that Myth would impose a single
output format, to which every source must be scaled  (I'm happy to find that
impression was mistaken),  so I was concerned about the CPU burden of
deinterlacing 1080i.

I'm still thinking about XvMC.  I expect my CPU is buff enough so I
shouldn't need it, but CPU cycles saved means cooler and quieter.

Ah.  I get it.  :-)  Thanks.

Yes, it's a single box.  I figure it just needs Internet access, and access
to some photos archived on another computer.  (When the day comes, I'll
either cough up for 802.11n, or - urgh - pull the wires.)
