Anynet+ switches HT-C6600 to Digital in when TV is turned on

Sorry for the delay in response. I had to go test this a little and speak to a few people to re-create this.
(Insert "how many geeks does it take..." joke here)
The design of Anynet+ is that it allows the devices to communicate when certain commands are sent.
1. For instance, let's say you turn on the Blu-Ray system. It's logical that the TV would need to be powered on, so it would do that. However, just because you turn off the Blu-Ray or HT system, that doesn't mean you're necessarily not going to watch TV. So it's based on a bit of a logical structure.
Blu-Ray requires the TV to be on - it powers on the TV and switches to that input.
The TV doesn't require the Blu-Ray player, so it waits for your command.
(However, if you do power it on, the TV will go to that input)
Likewise, just because you're done using the Blu-Ray player doesn't mean the TV watching is finished, so it won't turn off the TV. But if you turn off the TV, you won't be using the Blu-Ray player, so Anynet+ will turn off the Blu-Ray player also.
We can substitute Blu-Ray player for HT systems as well, since they're both devices on the Anynet+ network, but I wanted to give you the perspective from one device to the other.
2. The default input for the HT system is D.in. When you turn on the HTS, the HDMI-1 cable image displays briefly before defaulting to D.in. The cable box doesn't support Anynet+, so the HT System can't communicate with it, and as a result, defaults to optical.
The recommended setup for using the Anynet+ CEC functionality is to connect the cable box with HDMI to the TV for the video, and then the optical from the TV to the HT system. This will also allow you to control the HT system with your other remote.
3. "AIR", or the tuner, is an "always on" connection, as is "PC". Since more people would be apt to have an antenna hooked up to the television (rather than a computer, at least for most people!), the tuner is the default input if a signal drops out. You can avoid this by switching to a different input first before powering down something attached to the HDMI inputs, but if the signal is lost, Anynet+ will default to the "always on" connection.
You're not the first person to ask this, but unfortunately, I don't have a better explanation or a solution that would change that functionality.
