Bah! I tried to record the Three Stooges Marathon on AMC back on New
Years day and every single recording was ruined by ending about 40
seconds early, so yeah, it happens. I guess it probably is asking too
much for TV networks to be accurate to the second based on a schedule
posted weeks in advance. If I knew then what I know now, I would have
set the program with the GUI instead of MythWeb and set a per-show 120
second pre- and post-roll which, as I understand it, would have forced
the scheduler to alternate encoders rather than recording everything on
encoder #1.
