Ralph,
If it's clock skew, have you got ntp working on the recording machine?
I found that recording 3rd Rock on ITV2 (2 consecutive programs, each
30 mins) there was almost never a problem recording (maybe 6 out of
the 120+ episodes had the first 10-20 seconds of the second show
recorded at the end of the first recording). Using my DVB card, there
is a second or two 'missing' as one recording ends and the next starts
(not a problem for me).
If Enterprise is on at the same time each week, you could also use a
manual recording instead to record the full 2 episode length each week
On your idea, I think this would be a very useful feature to have the
option of using, however, if you have several recordings in a row it
could get to be a pain to navigate through the file to individual
shows.
