When I called Pioneer and spoke to a very knowledgable man, he specifically said that this receiver has HDMI pass through. The only reason it is not performing this function is due to the Comcast Motorola cable box which many have mentioned on the net as having the same problem. He claimed it did not have the proper HDCP keys. Video upconverting a crappy picture is still crappy...is it not. Kinda like an out of focus picture. No matter what you do its still out of focus. The audio link cable is some fancy cable to push the audio from the receiver to the TV. I did buy the Hi-speed HDMI cable from Mono too.
Depends, personally I think there's a little bit of difference up converting 720P to 1080P, but I'm also using a different receiver. Upconverting 480 to 1080 or a larger difference like that can be hit or miss. I think my receiver does an adequate job of doing so and I think there is a difference when I play a regular DVD through the Oppo blu-ray player, since that up converts as well. Neither will look like an out of focus picture if your receiver is doing what it is supposed to and isn't terrible, at least in my experience. This receiver will pass both audio and video via HDMI through? I'm going to have to look at the manual again because I definitely didn't see that when I took a quick look through.
Can you post a link to this cable? So you're saying you're connecting the motorola box via HDMI directly to the TV. Then connecting an audio cable from the TV to the receiver so that you can choose to use the receiver for audio or the TV speakers, and also bypassing the receiver completely for video?
