Composite Media

Question

Win TV-PVR-USB2 product. Can not receive anything from Composit Input connections. Works well with TV RF input.Used XP and VISTA operation systems. Have also tried to use Nero 6 for input control no video input. What do I have to do to get input from the Composite cables. Also the Remote does not have any effect on the unit. Bought this unit for converting Digital movies and VHF tapes to CD or DVD. the TV portion was just extra.
