[mythtv-users] Does anyone see occasional system lockups while editing?

Before watching a program, I like to create a cutlist from the
commflag results, and then fine-tune the cut points.  About 1 or 2
times out of 10, the whole machine will hang while I'm in edit mode,
requiring a hard reboot, with no suspicious log entries.  Frontend
details are:
  o Zotac IONITX-C board
  o running nvidia 190.53 drivers (but same behavior on at least 5-6
previous driver versions)
  o using VDPAU profile
  o running trunk, but I believe this has been happening since I was
running 0.21 (with the JYA VDPAU backport)

Editing on the ION frontend tends to be sluggish when jumping around.
I have the feeling that the hangs may occur when I skip around "too
fast", i.e. pushing a button before the previous seek converges on the
target frame.  It makes me feel like there is a VDPAU-related race
condition that results in the system locking up.

I'm interested in digging into this, but first I'd like to find out if
anyone else has been seeing this kind of behavior.
