[mythtv-users] Missing QAM channels

Since mythtv 0.20 I have noticed some QAM-256 channels missing after I 
do a scan.  I suspected that my provider (Cox) had encrypted these 
channels, but after talking to someone with a TV set with a QAM tuner 
I'm suspecting that mythtv is not seeing these channels for some reason.

I don't believe it is a hardware issue because I have a friend using an 
HD-3000 that is having the same problem (I use a DVICO Fusion Lite).

To work around this, I was trying to insert the channel into the channel 
table based on a back-up copy I had from when I was able to receive the 
channel in question.  After my SQL insert, the channel shows up in the 
mythweb channel editor, but mythtv will tune to either the channel 
before or channel after.  I've tried using mythtv-setup to scan only the 
frequency on which this channel is located, but of course it doesn't see 
any channels/transports on that frequency.  Any suggestions?
