I don't know whether this was done with any intent to foil DVR sofware
such as Myth (I doubt it), but I noticed a lot of this in my recordings of
the Olympics last month on NBC.  Commercials were often not flagged (some
were, some weren't) but I wasn't having any problems with other shows.  I
started looking closely and noticed that the commercials which were NOT
skipped were preceded by a significantly shorter "fade to black" than
usual.  Maybe that was it, maybe not.
