[mythtv-users] Frontend crash viewing HD-Firewire cap

[Jeff Wormsley]

I recorded a show from the firewire port yesterday.  It plays fine in 
mplayer and in the preview window when viewing recordings, but if I 
select it to play, it crashes the frontend completely.  Here's the 
output from a -v all run, with some (***) comments interspersed:

(***) This is one of the least informative error messages I have ever 
seen. :-) 

I have tried just about every combinations of settings imaginable, and 
it always crashes the same.  I suspect it may have something to do with 
my problem with the nvidia drivers for my FX 5200.  I am stuck running 
6629 because 7167 and 7174 don't display correctly on my system.  But 
under 6629, running things like glxgears crashes X (not just the app, 
but all of X).  Any standard def stuff, such as things captured on the 
PVR-250 play fine.  I can open the .nuv file for this recording in 
mplayer and it plays fine.  But not within myth.

Any clues?

Thanks,
  Jeff.
