It seems it isn't quite doing what I thought.  It >is< recording the 
full time (I got burned -- and confused -- by shows starting late). 
But, myth seems to be confused about how long the particular recording 
is.  In fact, it seems to be off by about 1 minute for every 5 minutes 
of recording, leading to 30 minute blocks looking like 23'57.  Sometimes 
when I hit the skip back button on the remote to skip back 10 seconds, 
it actually skips forward a minute or so, as if it is trying to skip to 
the "right" place.

Has anyone seen this before?  I haven't configured anything differently 
than from when it was working (that I know of...).

Thanks,
Eric
