Oh, and a bit of info that can prove useful:
Core 2 architecture = best
Core architecture = better than Pentium 4, but still garbage (yeah, P4
is worse than garbage)
Core != Core 2
Core Duo != Core 2
Core 2 != Core Duo != Core 2 Duo
(Duo means dual-core, "2" means great processor.)
Intel, master of marketing, purposefully named the Core 2
architecture--which they knew would get a lot of media attention as the
best out there--to be very similarly-named to the previous "stop-gap"
architecture (Core) and especially dual-core versions of that
architecture (Core Duo) so that "normal" people would hear they're
getting a Core Duo, dual-core processor and think, "Hey, that's the one
they say is the best. I'm getting a great deal on this dual-core CPU."
Reality doesn't count--only customer feelings.

Oh, and BTW, quad-cores available today are really 2 dual-cores stuck
together. You cannot buy a true quad-core x86 CPU today. Does that
mean it's bad? No, if you can use 2 dual core CPU's, it's great if you
only have a motherboard that supports a single CPU. However, once real
quad-core processors are available, they should be much more efficient
than dual-dual-core processors at tasks that are well-suited to
multi-core processors.
My recommendation for an HDTV frontend is to go with a Core 2 (Duo or
otherwise--yes, the Conroe-L is a low-cost single-core Core 2, so they
do exist, but you're unlikely to find one unless you look very hard) or
an Athlon 64 (or Athlon X2). I don't think it's a bad idea to get a
dual-core, either.
