IMO, if you're *using* LiveTV -- instead of just bypassing the box and
tuning directly on the attached TV/Monitor -- you're likely doing it
because you want to be able to use the features... which, of course,
you couldn't, if they weren't there.
I personally don't ever see that changing, at least not from the
primary developers as I read them.
