Clint,
Hi, and thanks for the review. I was happy to see a review of something that I own!
I finally got around to reading it this morning. One thing caught my attention right off, and I think that it's a misunderstanding. You state that it has four HDMI inputs, and that the front panel HDMI input disengages one of the inputs on the back panel. The VSX-23 actually has five HDMI inputs, and I don't think that any of them override each other. The back panel has four inputs ("BD", "HDMI 1", "HDMI 2", and "HDMI 3"), while the front panel has one ("HDMI 4"). The "BD" and "HDMI 4" inputs are fixed and are not assignable to any other input.
I have not actually connected an HDMI input to the front panel, so my statements are based upon my understanding from what I've read and the set-up menu on the unit. Did you test it and know for sure that the "HDMI 4" front panel input turns one of the others off? If so, which one?
Thanks.
Adam
