I'm getting a Sony 34XBR960 and was trying to figure out how to set up the PIP (Twin View) connections to be able to watch 2 different channels at once. I understand that only the left picture is HD. I have Comcast in ATL.
1) Do I split the cable before the HD STB and run a line from the STB to the TV (HD signal) and run a line from the splitter to the TV RF input?
2) Comcast can put in a CableCARD instead of the STB (won't get PPV, VOD, or menu) but is it possible to see two different TV channels in PIP with a Cable CARD?
