why hook your dvd-video to your receiver?

Thanks Fishcall for starting this thread,because I have been wanting to know the answer to this question and have not got around to asking it!

2 primary reasons:
1) It's for wife and two infants.
2) My old Panasonic Plasma has only 1 component video input.

Rather than to switch through inputs on TV AND A/V selection on the receiver, I have my AVR perform the up-video conversion. Therefore, my wife and kids have to hit only one button to turn on every thing. However, they sometimes turn the remote 180 degree b/c they turn to talk. Thus, not all components get turn on. This is when they know what to do to fix the problem. I try to keep things simple for them as much as possible. Sure, you lose some signals, but to my wife and kids, they couldn't tell the marginal difference. High-end interconnect cables with power conditioner help.

My Sony only has 1 set of inputs. Therefor, I need the receiver to combine all of my OSD's into 1 output. I have the preamps osd, dvd osd and the satellite. I have to put the dvd through the pre to see the osd. Yeh, I know I'm due for a new TV but this $900 32" sony won't die....
