I'm using comcast cable and have connected it to my pchdtv-5500 card. So
I've scanned the channels with QAM256 and find a good selection of
channels.
Livetv always works, but recording always fails.
My log file shows:
2006-12-05 16:48:17.433 DVBTuning Error: Could not find dvb tuning
parameters for mplex 32767
So, the channel db has the proper entry:

1 row in set (0.00 sec)
But the mplexid table dtv_multiplex doesn't have an entry for 32767.
Is this a problem with the scanning when running mythtv-setup?
Or is this a problem with the zap2it listings?
If it is a scanning problem do I need to build up my own channels.conf
(even though it appears that with .20 this is no longer needed:

Cards).
Thanks for any help or hints!
