[mythtv-users] MythTv freezing system

[Jeremy Owens-Boggs]

I have just installed MythTv on a Dapper-Drake system.  Older Computer,
1.8ghz, 512mb of ram.  I think I got the backend configured ok, and xawtv
works, but when I start mythtv or mythtv-frontend, then select watch tv, the
system freezes up and the screen goes black.  I have attached the output to
the terminal, the last enteries are

color,
            probably due to a driver bug or limitation.
            You might not get any video, but we'll try anyway.
