I used to be able to play a DVD in the DVD player for the kids and receive the audio through the radio. I know there is a switch that you have to slide on the DVD player in order for it to work through the readio. It used to work fine and I would always receive the audio on the same FM setting (I forget which setting right now). Then over time I would sometimes pick it up on a slightly different FM setting. Then sometimes it would be on the original FM setting but very weak. Now it won't come in on any FM setting. Anyone else ever had this problem? What was the fix?

Thanks,
Geoff
