I still haven't seen retail for the Polk but $200.00 for everything seems like a good price. You won't be able to run video to the receiver, it's not set up for HD. Keep your video directly to TV. You can use either optical or coaxial digital connection from Blu-ray or cable/satelite receiver, this will allow you to get 5.1. You'll need a digital connection for
5.1. You won't be able to receive the higher rez audio from Blu-ray (DTS-MA/Tru-HD). As you say though it will let you hear some surround sound and you can always upgrade when the money is available.
