I recently hooked a new Samsung DLP up to my HD cable box and my Yamaha 5640 receiver, and quickly learned that I could not get PIP. I went to Samsung's web site and found this:
"Generally, PIP (Picture in Picture) does not work with cable boxes. Here is the reason:
PIP televisions have two tuners. This allows the PIP TV to display two separate channels simultaneously, one in the main screen and one in the PIP. However, cable boxes can only unscramble and send the signal from one channel at a time to your TV. As a result, PIP - which requires the signal from a second channel - doesn't work.
With that said, there are some ways around this, but they usually require an A/V specialist and some tricky wiring. You may want to consult your cable company for information about this."
Well, with my cable company, you don't consult: you hold for as long as ever you'd like, then you hang up. But I do hope someone here can help. And I can't believe that the (very large, I'm sure) percentage of the tv-watching population that uses cable boxes can't get PIP ...
Thanks much, JJ
