Did you use an HD-2000 before, or is this your first foray into Myth-HD?

You might try current CVS (if you're not) or DTK's HDTV recorder patch 
from here: <http://www.mrl.nyu.edu/~danielk/mythtv/>, which is a big 
overhaul of the ATSC backend.

You might also try recording stuff and watching it later, rather than 
Live TV.  Yes, live TV needs to work properly, but most of the Myth HD 
developers don't use it much.

They may be in the same location, but they are different frequencies 
with different licensed power.  What part of the country are you in? 
You might check the AVS forums <http://www.avsforum.com/>; there's one 
specifically for HDTV reception with threads for different cities.
