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.
