Comment(by anonymous):

 Setting VDPAU_TRACE=1 causes Mythtv to crash in
 VDPAUContext::CheckCodecSupported. Without setting it, playback is
 perfectly stable (for me at least). I fail to see how that is a Mythtv
 problem.

 Jake - if you want to help track this down, as has already been noted, you
 need to try and grab a more informative backtrace (see the docs) that
 indicates where the seg fault is happening AND provide the associated
 frontend log (-v playback) that puts it in context (i.e. what the frontend
 was doing to trigger it).

 If you want to add the VDPAU_TRACE information, try adding "return =
 true;" at around line 1484 of util-vdpau.cpp. That should give you
 playback of recordings - still fails further down the track on live tv
 though. The extra trace information may not be useful if it is a mythtv
 bug though.

 (p.s. and make sure you're up to date with trunk.)
