Thanks for the reply.  I guess I'll answer the last question first:  
uname -a shows 2.6.20-1.2944.fc6 for my kernel.  If upgrading to a newer 
distro would help, like F8, then I'd do that.  As for the lineups, are 
you recommending something like this?:

       CableBroadcast = my "analog" channels (2-99)
       CableDigital = my "OTA" channels (HDTV channels, etc.)

I always wondered if having only 1 lineup was going to cause problems.  
Sounds like that might be the case.  Could the fact that I have my TV 
format set to NTSC and the subtype on the analog portion of the pcHD500 
card set to ATSC be causing some of this too?
