Comment (by Peter Bennett <pgbennett@…>):

 FYI - this may help in trying to track down this bug.

 When I first installed MythTV, live TV was working fine. I would get the
 "Error Opening jump program file buffer" only on channels which were not
 carrying a signal.
 After a few weeks and many tweaks, I found that I could no longer get Live
 TV. When I started Live TV it would start on a home shopping channel, and
 any other channel I selected resulted in "Error Opening jump program file
 buffer". Then the front end would crash. After restarting the front end I
 was back in the home shopping channel. Scheduled recordings were fine so I
 knew it could get the other channels. When I tried switching channels a
 zero length mpg file was created in the LiveTV directory before the crash
 occurred.

 After tearing out my hair for a few days I found a work-around solution.
 I looked up the channel id of a good channel I actually wanted to see by
 looking at the channel table in mySQL. Then I shut down the backed and
 updated the default channel this way:

 {{{update settings set data = 1021 where value = 'DefaultChanid';}}}

 I started the backend and then the front end. Now live TV works perfectly
 and I can switch channels as much as I want, although I have not tried
 that home shopping channel again.

 I think it was tuning to the home shopping channel because I had tried
 going through all channels to see what was available, and I probably left
 it tuned to that one.

 I do not know what is special about that home shopping channel that caused
 it to be unable to switch away from it. Perhaps because there were no
 program listings for it.
