8096	Music Only channels/still picture flag cause jump program error	mia1dolfan@…	Peter Bennett	"""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."	defect	closed	minor	unknown	MythTV - Video Playback	0.22-fixes	medium	fixed	hdhomerun tuning jump		0
