This seems pretty basic, but I didn't have an answer for it, so I'm turning to the "HTF." I have a friend who has a Panasonic DVD-R31 DVD player and she's trying to connect it to an older RCA TV that only has a coax input. Is there any way to connect this? Would a VCR that has RCA video and sound inputs help? Is there some kind of converter available? Or is a new TV the only option? Thanks.
