Give me the model number of your HD reciever and I will tell you if it is an HD one or not. Also, you will not benefit from 1080p unless you are going to sit 4 feet from a 42" TV, and even then, it might be hard to tell.

I don't think it is HD. The blue ray player has a HDMI port?? I don't know anyting about this stuff. IF I buy a tv with a HD tuner, does that mean it will convert it?
