I really wish HDMI had established some branding separation for receivers that would differentiate HDMI video switching from true (audio/video) HDMI. I've lost count of the number of products that I've had to dig through manuals and spec sheets to figure out that their HDMI implementation doesn't do audio - and every one of those has "HDMI" silk-screened on the front panel. The GTP-870 is just one more example of a surround processor that includes HDMI without using the audio side.
