In an ideal world, where all hardware and software works as specified, I
would agree. But it's not.

In my case, at the scheduled end of the recording, MythtV recognizes the
problem by writing something like that in the log:

"Poll took an unusually long time 4907229 ms"

Why not give up after 10 seconds and restart the recording, if it's a
one-time only recording? That would not fix my hardware or software
problem, but it would be much easier to live with it. And it should not
be too hard for MythTV to do this.
