Regards to point number 2, Satellite providers are still working off version 1.0 of HDMI interface and the receivers are being built to version 1.1. Net result, until Satellite companies do a firmware update to match up the two, you cant use the receiver as a pass through for digital tv. If there is an impending HDMI version 1.3, it will probably make matters worse...
This issue is pretty much obliterating the HDMI switching capabliities of this generation of HDMI capable receivers. Making them a very expensive mistake since the HDMI switching capability is what makes them so expensive in the first place.
The saving grace is that the HDMI interface seems to work flawlessly with DVD players. So maybe you can have 2 DVD players and switch them throught the amp while you wait for the cable companies and receiver manufacturers to get on the same page. ;-)
