TVs and DVDs

Well, I got a new dvd cleaner and cleaned my dvd player that I use when I'm on the treadmill. No sound. I put in the dvd side of the Bo Bice cd. No sound. I think my next step is to hook the dvd player up to another tv to see if it's a problem with the dvd player or cord. The player is a lot lighter to carry to the other tv rather than carrying the tv to the antenna to see if it's the tv that's the problem. But that might be in my future as well.
