Doesn't HDMI have a handshake mechanism, and checksums to make sure the bits are correct? If your HDMI hits the maximum length, it can be repated. The differences between analog and component is where does the D/A conversion happen. You had better set the output on your receiver to do the native resolution of your TV so that it doesn't scale twice. If you don't, it will rescale, *regardless* of whether you are using component or HDMI. There are plenty of plasmas out there that do 1024x1024, but there are ones out there that do 720p native resolutions. While what you said may be true of some plasmas, it is not true of all plasmas. Under the scenario of a 1024x1024 plasma, regardless of what you use, component, or DVI, the TV will still have to scale a second time if the source mode doesn't match the output mode of the receiver. It is moot point. You should learn more about MPEG compression before you try to explain it. The Motion Picture Encoding Group (MPEG) compresses the signal with a Discrete Cosine Transform which puts as much information in the left hand corner of the screen as possible. This reduces spatial redundancy. The compression technique you are speaking of is very rudimentary and not nearly efficient enough to do the job. With dish's compressed up the wazoo SD signals, there isn't enough information to do a good job scaling the picture. Oddly enough, I've found that using the composite cable on the compressed SD picture works well, and precisely because everything gets combined and things get smeared a bit. The result is that smeared colors look better to me than blotching and solarization. Aside from what you have said TechnoCat, olgeezer was correct in what he said.
