Mythfronend causes Xorg to crash/restart when starting playback

[Ben Kuhn]

Binary package hint: mythtv-frontend

Release: 10.10 beta
Version: 0.23.1+fixes26192-0ubuntu1
When attempting to play video, either live tv or recordings made on the backend, X crashes and GDM restarts. There is no video playback at all. I can reproduce the issue on both of my frontends. One is running an ATI video card, the other is Via so I do not believe the instability is related to the video driver.

Here's the relevant snippet from the mythfrontend log file:

Howdy, and thank you for helping to improve MythTV and Ubuntu by opening this ticket. Others that have encountered a similar problem have noticed that changing playback profiles to one that does NOT use XvMC has resolved this issue. Could you please try that, and perhaps other profile options, and report back?

Thanks!

I'm out of town for the weekend. I'll give it a try when I get home.

I had the same problem with Xorg crashing when watching 1080i video only -- strangely, not 720p or SD. I switched from whatever the default profile was to "Slim" and that worked perfectly. Thanks!

MarcRandolph,

Changing from XvMX to Vdpau stopped the crash out of X:
