You mean for sound, right? My dad's new TV has that. It even has an optical digital out, and when you tune to a digital TV channel via antenna, it will feed your receiver the digital audio to split how it likes.

The inputs and such are definitely annoying. Like Tony said, discrete inputs and a programmable remote are your savior. I've got a Pronto set up for settings like 'DVD' and 'Tivo', and the TV and receiver inputs all change accordingly.

This confuses me though: "If I switch between television inputs, the sound for the dvd is still playing (since there is no digital input on the TV.)" The problem is not that there's no digital into the TV, but that the receiver has not been either muted or switched to another channel. If you mean over the airwaves TV, which your receiver won't be getting directly, then the audio is going to go through the TV only, in which case you'd have to mute the receiver. Of course, I have no idea if I'm understanding you correctly. I'm probably way off

Just curious, but what do you mean you don't have HD? Do you mean your TV doesn't have a built in tuner, you don't have a tuner at all, or you don't have an antenna/cableHD? If you have an antenna, don't you have HD? I know it sucks not having many HD sources, but we have an old antenna on our roof (supposedly the older antennas get the HD signal better or something), and our TV has a tuner built in. The NCAA championship game was the first thing we watched in HD. Incredible. Since then I've even been watching ER with commercials just because it looks so good.
