I also thought that HDMI has many problems, like you have, too. My idea is: video and audio and other stuff are separate cables. The video cable will only be sending the digital RGB video data, with the wires for the pixel data and pixel clock, as well as power and ground and vsync. I think it is helpful for the video signal to be digital, but it does not need to be as complicated as HDMI. (The audio cable can be balanced analog audio signal.) It is not only HDMI; many other common things are too complicated (than they should be) and often have other problems too (you mention some of them, such as HDCP, but there is many more problem than that). (Someone else wrote: "The sad fact of the matter is that people play politics with standards to gain commercial advantage, and the result is that end users suffer the consequences. This is the case with character encoding for computer systems, and it is even more the case with HDTV.")
