Juust got this reciever this week and need help in two areas. 1. When I watch DVD's the subwoofer sounds weak even at FULL volume and the bass is set on +6 on the reciever, for DD and DTS movies. If I hit the S-direct switch the thing blew the pictures off the walls. I had to turn the subwoofer down to 1/4 volume. Is this supposed to be this way? 2. I have a sony 5cd changer 8 yr old all in one hifi that I would like to hook up to the reciever for the kid to play wiggles on. The DVD player is hiddenbehind the TV to sop little probing fingers, so its hard to get to and keep swapping discs. The prblem is there is no line out or audio out. Only the hedphone out and L and R speaker connectors.Can I plug this into the Marantz 6200? I think the sony is rated at 15W RMS.
