Yup, all that would be great.  Except the broadcasters don't actually
do that.  They populate the PSIP feed pretty much with the same data
that is used by SchedulesDirect.  In other words, if a program runs
long, then the ATSC guide will be just as screwed up as the
SchedulesDirect guide.

Unfortunately, the broadcasters don't really have much incentive to
make this system work well, and in fact they probably wouldn't have
done it at all if they hadn't been compelled by the FCC (their digital
carriage license requires it).
