[mythtv-users] video issues with PVR-500

[Josh White]

I went away on vacation for a few days, and when I returned, something had
happened to my entire home network.  My router needed to be completely reset
and reconfigured before I could get anything working in that regard, and all
of my machines, including my mythtv backend were in a strange state.  My
backend was totally unresponsive to direct input from a remote, keyboard,
mouse, network, etc.  The only way I could make it restart was to force it
to power down with the power button.  When it restarted, I saw a kernel
panic and it stopped responding on the initial reboot.  I forced another
restart, and it booted this time.  My windows 7 machine was in a state where
it failed to start and was attempting a recovery, and an OS X 10.4 eMac was
unable to connect to the network. Once I got my network reset and
reconfigured, and all my machines rebooted, I noticed that my backend had
made no recordings during the time I was away, and those made since I reset
everything had bad video (though the audio seems fine).  I'm not sure how to
go about diagnosing this part of the problem, so I started by running
mythfrontend from a terminal, starting a livetv session, and then exiting,
and here's the output:

Error in my_thread_global_end(): 2 threads didn't exit

So live TV played good audio, and it played the video, it it was like it has
a bad signal.  Whatever was recorded, seemed to play back smoothly, its as
though it's just producing a bad signal.  I've never had this trouble with
either of my two PVR-500 cards, and any time I can't make myth work with
them properly, I test them using vlc to tune a singal manually, and that's
always worked.  When I try it now, VLC simply crashes.  I can view live tv
straight through my TV (using the actual tuner in the TV) and things look
fine.  I haven't changed anything physically, and everything was working
when I left on Friday.

Where should I go from here?  What other log files, etc. should I be looking
at?  What part of myth should I attempt to reinstall to force a good
configuration? Any other tips?  Please help!  let me know if there is
anything else I can post that would help identify the problem!

Thanks,

 Josh
