Actually, that is why I am still using a VHS VCR.  The DVD recorder (with
hard drive) I bought kept stopping when I would try to record something.
So I gave up and went back to the old VHS.

The interesting part is not (mostly) which bits were set but rather that
Microsoft still claims their software was acting as intended by
purposely suppressing recording for ANY combination of flags that can be
set in the stream.  That is, they admit they have willfully given
broadcasters the ability to turn off recording (and commercial skipping)
to Vista Media Center.

Imagine purchasing a VCR with this feature.  Most people would pay less
for it if they knew.
