Yes, that would work.  The lack of XvMC support was what initially put
me off the Radeons, but I guess it's just a matter of throwing enough
CPU at the problem so that it stops being a problem? (and I guess that
the fact that I'm looking at DVB-T rather than analog helps too).

What kind of CPU should I be looking at if I want to make sure I can
play something back while I'm also recording on the two DVB-T cards?
