New description:

 Watching LiveTV from HDHomerun tuner fails every 2-3 minutes with a crash
 on mythpreviewgen. Can happen immediately after a channel change or just
 by watching for some time (variable). Change of FS from ext4 to JFS makes
 no difference.

 MythTV drops back to menu with message "Video frame buffering failed too
 many times"

 Frontend logs contain "Waited 100ms for video buffers dDAdAALAAAADdAAAA"
 (last ID is always different)

 Last error from front end:
