The image adjustments are available for any analog 480i source, over any input--composite, s-video, component. I don't know why it's limited, I agree it's kind of silly.

To preserve the aspect ratio of the source? The real problem is that the scaler's stretches 4:3 by default and it doesn't appear that you can defeat this and leave 16:9 content alone. The 4:3 setting makes sense, if you think about the purpose of the scaler--to upscale SD sources, which are usually 4:3.

The tuner over HDMI scales to 10801 internally much better than sending a 480P signal to the 82's scaler to make 1080i. I dug out my older Sony progressive DVD player set it 480i over component and agree the Pioneer did a fine job of upscaling that.
This makes perfect sense, actually. To get to 1080i, the tuner simply scales the 480i signal up, leaving the interlacing alone, in one step. Getting to 1080i through the 82, on the other hand, involves many more steps--first, the tuner deinterlaces the 480i signal, then sends the resulting 480p image to the 82, which scales it up and reinterlaces it to 1080i. Those extra steps involve significant signal degradation, which is what you're seeing.
Upscaling the DVD player, on the other hand, all takes place in the 82's Faroudja chip in one step, which is why that looks pretty good.

Changing the brightness and contrast doesn't mean the scaler is "pretty poor overall." It just means you had to change the brightness and contrast to get good PQ out of your TV. Although I do agree that you don't want to use the scaler for everything. It works well with 480i SD sources, which is what it's there for. But as with anything, it's garbage in, garbage out. If you're expecting a miracle, you're going to be disappointed.
