I haven't been able to view anything from my HD-3000 card yet, the
furthest I've taken it is that QAM64 scan in mythtv-setup, I was
hoping to find someone on this list that could possibly point me to a
resource where I could find a QAM64 frequency table or instructions on
how to create my own so I could fine tune the channels, get the
call-signs, and edit the database manually.

In other EXCELLENT news, mythtv can now use firewire to record HDTV!
It didn't like the Broadcast option, however setting the firewire
settings to P2P and 200Mbps did the trick. I read in numerous places
people saying "set the speed to 100Mbps, that is more than plenty, and
mythtv will auto set the transmission rate blah blah"

Project HDTV = 40% complete now :)
