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
