New description:

 My GPU has really bad performance with the open source driver, and HD
 playback was jerky, so I switched to the proprietary driver. It is very
 fast, but I get crashes with mythtv:

 1. With OpenGL it crashes when I start any TV, live or recording. Log
 including stack trace is attached. Main part of stack trace:

 {{{

 }}}

 2. When setting the renderer to xv-blit, it works, but the deinterlacer
 gets stuck at "One Field" even though I configure a different one, and it
 sometimes crashes when I exit video playback. I then get a straight
 segmentation fault, no stack trace.

 The OpenGL problem (1) is the main issue, but I though that (2) may be
 related, and it's the current (bad) work-around.

Comment:

 We can't do anything with a backtrace if you're using stripped binaries.
 Recompile MythTV, and leave the debugging symbols in.
