You are running into a standard problem.

Audio switching for advanced stuff (like digital surround sound) must be done on the audio receiver/amplifier, and video switching for advanced stuff (like YPrPb component video or digital video) must be done on the TV.

So for most folks, you literally have to switch inputs twice. Once on the receiver/amp, and once on the TV set.

What a pain in the ass.

Work arounds, or situations where this does not apply:

1. Your audio receiver/amplifer also contains video switching and video up/downconversion for all of the video types that you use. In that case, you plug everything into the amp and run one set of video cables to the TV. However, only the most recent and most expensive receiver/amps will have YPrPb component video switching, and I don't know if any of them have digital video switching yet.

2. Your TV does audio switching for all of the audio types that you use (analog stereo and digital surround). I don't know whether it is common for TVs to do this or not. My TV will do audio switching for analog stereo, so I use that. I actually haven't upgraded to a digital surround system yet because I really like the convenience of only needing to switch the TV input and leaving the receiver/amp alone. I get 4-channel analog dolby surround through those switched analog inputs, and it keeps me pretty happy even without the 5.1 digital surround.

3. You have a programmable universal remote, and both your TV and your receiver/amp have what's called discrete codes for each input. Meaning that you can send a single infrared code to the TV set saying "Switch to input Q" and you can send a single infrared code to the receiver/amp saying "Switch to input Q", and map those to a specific button on the remote and have them both play when you press that button. As opposed to having to press "Input, Input, Input, Input" the correct number of times (which is what you would have to do without discrete codes). You're still switching inputs on both devices, but at least you're only doing it with one button.

4) Your receiver/amp and your TV were made by the same company and have an "interlink" system where you connect them with a communications cable of some kind. Such systems are designed to work intelligently and to switch to the appropriate inputs.

5) Your receive/amp has some sort of intelligence where it will switch to/from the digital audio input when it detects/loses the signal. So when you want to stop watching the digital surround on the DVD player, you simply turn the power off on the DVD player.

6) You purchase a third-party video/audio switching system. But that can run into money if you want high quality and a lot of options.
