    I've had the very same problem ever since I upgraded my P4 system to 
one using the same exact same MB, CPU and memory configuration except on 
Ubuntu 6.04.  I can tell you it has nothing to do with the video capture 
portion as it happens when playing back recordings too.  Like you said, 
it is extremely hard to track down considering it happens so rarely.  I 
don't have the problem when playing back over an 802.11g wireless on my 
laptop (a single core Dothan). 

    I've turned on -v playback on the frontend and all it tells me is 
that "video is behind audio".  It definitely isn't a heat problem.  The 
only thing I can think of is that there's a problem with either the dual 
core, or power throttling, but I haven't had any time to play with it.  
Something I've just thought of was to maybe disable XV and see if it 
does it? (`export NO_XV=1` in a terminal before launching mythfrontend 
in that terminal). 

    Let us know if you find something!
