My RCA model led32c33rq TV will only play videos if I connect it to the VCR/DVD player with the yellow composite cable, (not with the red, green, blue cables) but then it will only play in black and white. DVDs also play in black and white. When I reconnect with the red, green, blue cables, DVDs play in color, but videos won't play at all. Even when I switch the source to VCR on the VCR/DVD player, the DVD continues to play, when there is a video in the deck and it is (ostensibly) playing.
