Comment (by dekarl):
Replying to [comment:16 J.Pilk@…]:
> BBC Four (SD) is a part-time channel, and the News is its first item.
My recordings have a 2-minute pre-roll, so the possibility of bad
behaviour clearly exists. Somehow, ISTR, my earlier version avoided it.

> I found that I had sound and picture in the editor, and MythDVBcut has
created a good copy, so I'm not much worried. There are obvious
workarounds.
It all depends on how they fiddle with SDT/PMT when stopping/starting the
service.
The service should be signalled as present, but not running, when this
recording starts. Then on top of the hour it should switch to running in
the SDT.
I'm not sure what the PMT is supposed to contain while the service is not
running. But if we record everything on PMT update / stream start that is
good and issues can be fixed after the recording was made.
Your description sounds as if the stream may be present but not running,
too. So there is no addition of a stream and no automatic stream selection
is kicked when the service starts. Can you verify that the audio can be
selected by manually cycling through the audio streams without fiddling
with the file? (A test file would be nice to add to the collecting, too)
