MU_gz,

What you may want to do is hook everything up via HDMI to your new receiver. This will allow the sound to be processed directly to the receiver, and then hook up the receiver to the HDMI input of the television.

Soundbar: Bluray
Soundbar: PS3
Soundbar: Motorola DVR (Tho sometimes they work better directly to the TV, with optical audio from DVR to soundbar)

Soundbar to TV.

That's my recommendation, although it holds no weight over what anyone else would recommend, so if someone has a better suggestion, I'd love to hear it. Keep us posted.
