Are you sure that will work?  Are you absolutely certain that you're 
getting ATSC feeds from your satellite?  And, if so, are you absolutely 
certain that these feeds are unencrypted?  If the answer to either 
question is no, the HD-5500 (and likely--though I don't know the 
hardware--the WinTV-HD) won't work at all.  Feel free to ignore me since 
it sounds like you have some special setup, so you probably know what 
you're doing, but I just thought I would mention it just in case.

Oh, and BTW, the frontend is the part of Myth where the extra power is 
useful.  My system has 2 backends (AMD Athlon XP 2400+ and AMD Athlon XP 
2000+ with 1GB and 512MB RAM, respectively) each with 2 pcHDTV HD-3000's 
and one frontend (AMD Athlon X2 6000+ with 2GB RAM).  The only reason I 
have 2 backends is because I couldn't find a system (power supply and 
mobo) that could drive 3 or 4 HD-3000's without power issues (and, once 
I set it a 2nd backend, I liked the fact that it gave me a lot more room 
for hard drives/storage).
