 "jump program error" on frontend when tuning in any program on QAM-256
 channel 120.  This happens to be the "music channel" on Comcast in my
 area.  The myth front end displays the OSD, shows signal locked, hangs on
 a blank screen for a while, and then dies with the "jump program" error
 message.  If you enter live TV again it goes to the last channel tuned,
 and the whole process repeats.  I have to enter mythtv-setup and change
 the tuner to start on some other virtual channel number that does not map
 to channel 120.  This is the only channel that consistently fails to tune.

 I installed a fresh copy of myth on another separate system and observed
 the same issue.  I took a packet capture and I could see the communication
 with the hdhomerun device, it sets the channel, sets the target, the
 device starts sending a UDP stream, and Myth sends filter commands to tune
 the program....  I think it's not tuning in the right program.  I tried to
 change the backend to quick tune the channel, so it used the channel
 number instead of the PID filter, but ran into bug #7971.  I can properly
 view the programs on the channel using VLC.  In mysql I looked at the
 channels tables, the freqid and serviceid columns look fine to me.

 I have attached a "mythbackend -v all" log along with a clean packet
 capture (starting with a SYN and ending with SYN ACK - ACK).  I installed
 through Ubuntu 9.10, packages version 0.22.0+fixes22594-0ubuntu1.

 Thank you.
