Sorry, I didn't realize myth couldn't flag the start of a commercial until it
found the end.  OK, for this idea to work, then, you'd have to be watching 5 or
6 minutes behind real time (whatever the length of your longest commercial break).

You could use the play list for that, that doesn't sound like a big problem.
I'd be more concerned that you'll be abruptly stopping the playback of the
program you switch to during the commercial.  It could be pretty disconcerting
to keep switching away from a recording in mid sentence.

I feel the same way, but I know some people do like to watch at least some
programs in real time.  I do see what you mean about the lack of a use case for
this idea, though.  Basically the only people who would benefit from this are
people who are too eager to watch the show to wait through 1/3 of the show or
so before starting to watch it, but not too eager to wait 5 or 6 minutes.  It
does sound like a pretty small group.
