As an update to my post (#1798
) about issues when connecting to an S-A 8300HD cable box, and as a reply to batpig's post (#1802
As it turns out, changing out the cable with a supposedly inferior
one solved the problem!
My cable (of which I have 2 identical ones) is HDMI 1.3a / x.v.Color rated. It worked fine between my Samsung TV and the 8300HD cable box. It also works fine when between my Denon 2310ci and my TV....and between my BD player and my Denon and/or my TV. BUT, put it between the 830HD and the 2310ci and HDCP key exchange fails! (Sometimes is works, but rarely). Replacing it with a low-end cable I borrowed from work solved the problem.
I've since found out that one cable operator in NY was actually replacing people's Monster cables with cheap versions to rectify a similar problem! Go figure...the 8300HD or the Denon (or at least the combo) does not seem to like good HDMI cables?!? I'm going to borrow a friend's "el-cheapo" cable and try his, too....and I bet it will work.
I'm not claiming to understand it; I'm just sharing what worked for me.
The only completely wild GUESS I can make to explain it is that maybe the Denon is introducing a little bit of noise on one or more of the pins, and that the better cables pass that along to the 8300HD, which doesn't tolerate it, but the cheaper cables end up filtering it / rounding it off so it doesn't cause a problem. Or, to be fair, maybe the 8300HD is introducing it and the Denon doesn't like it. Again, only a GUESS. (I gave one of my "bad" cables to the appropriate department to look at when they get a chance, but I can't speak for their schedule as to when they can try to look at it.)
To address batpig's comment:

First, that is an interesting point about the Denon being a source and a sink. That may play into my guess above about noise being interjected -- maybe some sort of crosstalk inside the Denon b/c the Denon is playing dual roles??? (just grasping at straws -- NOT assigning blame).
Finally, to wrap this up for now, I can't speak for other manufacturers, but I know we at least try to test with the most popular brands of receivers, and if we hear of an issue we do try to duplicate it so we can address it. Still, in fairness, it's not practical for any company to test with every piece of equipment you may end up connected to...and that is why specifications exist and why testing to meet those specifications is done.
