Hi, just got the 30" Syntax dual-tuner TV and am hoping someone can help me with the PIP problem I have. I can get the small PIP screen to show up, but it only shows the same program as on the main screen. Since it is a dual-tuner TV I should not need the VCR to connect this. Here is my connection: wall cable to cable box (analog)in. Out from cable box to TV RF. I also have a Playstation and CD movie player connected via composite cable and S cable, bot work perfectly well on PIP. The only thing I cannot get going is watching 2 different TV programs. Does it have anything to do with the kind of cable box I have? Do I have to worry about A/V switches and such? I have both the main picture and second picture set to TV. I really would appreciate any help with this. Thank you so much.
