[mythtv-users] Freeze!

[John Biundo]

Desperately looking for debugging tips!  How would you go about tracking 
down this problem (see attached)?

I've upgraded my kernel to 2.6.15, and upgraded ivtv to 0.4.2.

I'm not really sure where the likely culprits are for this problem.  I'm 
not sure what facilities, libraries, or external technologies come into 
play in this scenario.

I'm sure there must be some wisdom on this list concerning how to go 
about isolating the problem.

Please take pity on this relative newbie who's spent countless hours 
getting MythTV up and running, only to be haunted by this intermittent 
freeze!  If you've got ideas, I'd love to hear them.  I'm usually good 
at taking general ideas and running with them, so even if it's just a 
hint, don't feel like it's necessary to write up the details, please 
just post it!

Thanks!
john

The problem in a nutshell: if I pause livetv for a while, then rewind, 
the frontend freezes.  Sometimes it comes back, sometimes not.  So far, 
very few clues in the log files (see below).

Hi,

I haven't had much luck (OK, zero responses, but I'm not complaining ;-)
to my earlier queries about my frontend freeze problem.  Googling
around, trawling through Trac, etc., have been largely fruitless.

Rather than search for an answer or a direct match to my problem, I'm
hoping I can get some clues so I can try to root around and work out a
solution.

If someone could please enlighten me, just a little bit, on the
following question, I'd be very grateful!

Is there a general description of what these mythfrontend messages mean,
and what might be some possible underlying causes?

2005-11-27 22:18:08.732 Waited too long for decoder to pause
2005-11-27 22:18:09.184 Waited too long for video out to pause

For what it's worth, there are usually a bunch of the "...video out to
pause" messages for each "decoder to pause" message.  It usually
happens, for me, after livetv has been paused for a while.  And perhaps,
after the pause, attempting to rewind.

Sometimes the frontend comes back to life after a very long freeze.
Sometimes the whole thing degenerates into a bunch of mpeg decode errors.

Anyway, hoping to get some clues that might help guide my
experimentation (e.g., trying a different filesystem, a different
kernel, a different version of mythtv, a particular debugging flag and
experiment, etc.)

Thanks in advance for any help.

Cheers,
john
