On the remote, does it have either a "input" or "tv/video" button? if not, try switch between the first and the last channels on the tv (see if it is there or not. Another way to do this might be to feed the dvd signal through the vcr (it may not be ideal but I think it could be done). Also I think they sell a video-to-RF(modulator) for people's tv that doesn't have any video input at all.
