[mythtv-users] HELP!! Have backtrace of frontend freeze, need help understanding it.

[William]

Replying to my own message. I finally got the system to run stable. I had to
upgrade to SVN from about a week ago.  My system has been running live TV
(music channels) for 10-12 hours at a time with no crashes. I really like
that I now have closed caption support. My deaf buddy wants me to build him
a system now. :)
