The unit is definately capable of working the way I want. It can be fixed in software.

Here is proof: Let's say I want HDTV with DVI-2 and S-Video outputs. I select HDTV and go into configure, select DVI-2 and exit configure. Then go back into configure and select S-video and exit configure, the unit is now configured with both DVI and S-video outputs active and set to the correct device. The problem is that if you now select DVD, which we will assume selects DVI-1, the DVI output will stay set to the DVD then next time you select HD-TV and you have to go do this configure stuff again.

I look forward to a fix. After thinking of various complex menu fixes I have a simple suggestion. Just leave the S-Video inputs active when in DVI or Component. If someone really needs composite inputs, they can use a $5 composite to S-video adaptor. This is a comprimise suggestion but solves my problem. Certainly better than blanking the outputs.
