I think the biggest problem here has nothing to do with hdcp or anything else, its more a lack of true conformity among all manufacturers, and the fact that this technology is by all real standards, new.. Come talk to me in 5 years, when it might have begun to show real market penetration in view-ship, and all manufactures will have had 2 or 3 real generational changes in their lineups of equipment, then see how many issues of this nature we have.
Anyone else remember hop the first 2 to 3+ generations of hd sets only worked with their specific hd decoder boxes and not other manufacturers? Same thing here...
I certainly don't remember that. When was it exactly that there were special converter boxes? Pretty much every box I have seen (and I started seriously researching HDTV in 2000 and bought an HDTV in early 2001) had component or DB15 out and every TV accepted that. It was only when DVI and HDMI started up that there began to be incompatibilities between sets and boxes.
As far as 3D. If you wait 5 years, no one will care because it is a gimmick that Hollywood is already starting to see reduced returns from. No content = no or very little home 3D. Now, if suddenly every movie is made like Avatar, things might be different, but since only someone like Cameron wants to spend that kind of money, the "3D" movies made will continue to not be much of a value add for moviegoers.
