I spoke too soon, but this time I have a stack trace.  It seems to crash
randomly when I start watching a recording or live TV, but never of the
first try after a restart.  I'm running 2.6.7 with XFree and the nVidia
6111 driver.  Based on the trace, it looks like an nVidia issue.

Any suggestions on how to fix this?
