I had it for a while on a couple of channels (including Fox--can't 
remember which other).  It seemed to occur for me due to the way the 
broadcaster had encoded the video.  During the commercial break (when I 
let it play through the break--i.e. when I stepped away for a minute), 
something would happen that would disable captions and time stretch, and 
I'd have to re-enabled them.  I never got to the exact cause (let alone 
a fix) because it stopped happening (I'm assuming because of changes to 
encoding), but I have a strong suspicion it occurred when there was a 
change to refresh rate (i.e. from 720p60 to 720p30) or resolution (i.e. 
from 720p60 to 480i60) or something.  If it's something like that, the 
fix will involve changing MythTV's code.
