Looking to take advantage of all Sony has to offer. Just bought a Sony WEGA 32XBR, and DAVC900 HT in a box. Bought the monster cable PIP kit. Has anyone setup PIP with premium digital cable set top boxes? I have a Motorola digital cable box, from ATT. Several people have stated I may need two digital boxes, and a A/V switch. If this is the only way to set this up? Would anyone have a cable diagram or first hand knowledge as to how to set this up?
