I don't claim to be an expert at all, but I know that when I change the signal on my 622 from 480 to 720 to 1080, my TV detects this change. That leads me to believe that there is some change going on there. Again I'm no expert, just making an assumption - and yes I know what they say about assumptions 
When you set the TV Type, the signal is SCALED to that resolution. There is a Broadcom chip in your 622 that does this.
Here is a paragraph of copy from a DVDO Scaler webpage:
Why does anyone need a scaler? Well, for one thing, it will generally do a much better job than your display or upscaling DVD player will when converting and sizing (scaling) low video resolution sources to your high resolution display. If your Standard definition sources like Cable or Satellite, VCR or Laserdisk look awful on your HD Television or projector, you can clean them up considerably with a high quality video scaler.
High end systems like DVDO also contain signal processing circuitry to improve the picture as well as scale(convert and size) it.
Really different ?
I would like to see how you define for yourself those two techniques.

What does this screen have to do with SD output?
No. I just don't agree that the 622 is outputting SD at 720 or 1080. That screen is for setting HD output but I don't see that it mean SD will be at 1080 or 720. I'm not trying to be smart or funny.
Either way, the end result is SD looks nothing like 720 or 1080 so it really doesn't matter I guess.

If it were outputting native resolution, then my TV, when in 1080i mode (does not automatically switch), would display a SD image in the top left quarter of the screen. The image fills the screen, thus the image has been resized to 1080.
The image comes into the receiver at whatever resolution it's broadcast. On the HD outputs, it comes out at the resolution you specify on the HDTV Setup screen.
How difficult is this? Are we all on drugs?

Yes! You are correct in that it does not LOOK like true 720 or 1080i content! EXACTLY! It has been SCALED and unless you have a very expensive processor to go with that scaling, the signal will look shabby to say the least.
Upscaled, scaled, or upconverted - they are all the same. The 622 DOES change it to the correct resolution, but the chipset is not able to process the picture in order to make it look good.
It will NEVER be the same as TRUE 720 or 1080 content, but it has been modified to tell the display that that is what it is!
No worries!
SD is usually horrible on any HD display, without a great processor to clean it up for you!

Dang, you mean they can't actually do that? ;-)
I love CSI but that trick ALWAYS makes me grit my teeth.

That's marketing having their way with terminology! What matters is whether there is a video processor in the upscaler/converter like in the Gennum and DVDO video processors.
The 622 scales SD to whatever you set on the TV Type, it just doesn't do it well.
This is why there are some here who are begging Dish for NATIVE PASSTHROUGH. This will allow the signal to pass untouched by the 622 Broadcom scaler and let the end user's equipment handle the video processing.
I'm doubt if there is Broadcom silicon scaler, it's all software transforming; read "made by Dish".
Time to reread specs of BCM7038 ( those two BCM7411 I think just doing H.264; OK, OK I will check them too ).
BTW, last day(s) new beta SW begin spooling for NEW Model ID, it have internal name "DP411" !

The BCM7038 is an advanced dual channel HD video/audio/graphics and personal video recording (PVR) chip that enables manufacturers to economically incorporate high-quality HDTV capability and PVR features into digital televisions, cable set-top boxes, satellite receivers and HD-DVD players. The chip's dual video/audio channels simultaneously support dual televisions, with independent picture-in-picture support on main and secondary. Advanced video and graphics features, such as on-chip 3D Y/C separation circuit multi-frame de-interlacing, and quad video scalars with single pass processing, significantly improve the HD picture quality, by removing unwanted noise and artifacts from the television image. The chip supports common PVR functions such as pausing live programming, recording, and forwarding and reversing through recorded programs, as well as incorporates software drivers to support industry standard PVR platforms, including TiVo® and XTV™.
Still not clear how embedded CPU involved in the scaling processes; could be heavily and require a lot of work for software developers.
