So, SD channels come in at 480i. HD channels may be 720p or 1080i depending on the channel.
This is why the native pass-through would be good for those of us who want to let our TVs handle the signal in its native form.
Otherwise, no matter what you select on your box, you are converting something. The only work-around at the moment, would be to manually change your settings on a per-channel basis... but that's more work than most of us want to do... so we compare them and leave it set at whatever looks the best, or at least the best for what we watch most of the time.

The fact that this feature is not in the 942, 921, 811 and 211 and is suggested with each new HD receiver, I am not sure how easy this feature is to implment. Bummer yes.. but I would personally place it in the feature bucket not the bug bucket.
All we can do is keep asking for it and hopefully the team will see the benefit of such a feature. It is on my list for highly desirable features.

I guess it could be that they have the hardware set to up/downconvert no matter what and the software just selects which path... and if that's the case, then a new board design would be required to implement the pass-through feature.
Depends on what they were thinking when they designed these receivers.

At the very least, though, there should be no reason the receiver cannot pass through the signal at the closest standard resolution. If it gets any 1080i signal, it passes 1920x1080i. If it gets any 720p signal, it passes 1280x720p...etc. Basically a hybrid passthru, switching to one of the 4 standard resolutions on the fly but not necessarily passing the signal exactly as it came down off the SAT.

Obviously Dish hasnt ever felt the need.
I've never lost any sleep over not having an HD receiver with that feature. And I've had a number of different ones. I'm not even sure I'd select that option in the menu even if it were made available. I suppose it would depend in part on the particular display as to for example how quickly and "seamlessly" it could re-sync every time you were simply channel surfing over various channels that were native 720p/1080i. Like with the Big 4 Networks where theres 2 of each. Or even more lower resolution options if you're surfing the OTA sub-channels too.
Not to say the feature shouldnt be included though just in principle for those that already know they'd use it.

The reason I have the receiver at 1080i is because my TV downconverts to 720 better than the 942.
Most would prefer their TV do whatever scaling is necessary since it is almost always better.

But I got no beef the way 720p source material looks even with the boxes set that way. Be it Fox, ABC, ESPN's etc. Certainly if I was worried about it, particularly when watching 720p programming for a lengthy period of time.. like 2 or 3 hour ballgames, I'd take the few seconds to switch the output on the source box to 720p to have a straight shot for the duration (and then back again afterwards). Heck even for a one hour show.. why not? We're talking a few button presses here.. not re-wiring afterall.
I just dont bother.. not because I'm too lazy, but because it just doesnt matter to me. Now obviously if I said to myself, doggone it it just doesnt look as good as it should, that would be different. But I'm not going to worry about it just due to principle.
Do you bother to switch the box to 720p if you're going to be watching that type programming for an extended period? I'm sure some people must if they're that worried about what the conversion process might be doing to the PQ.
Guess if anything I'm more worried about what the PQ of a given program might look like not based on what resolution it is, or what the STB is doing.. but whats happening at the broadcast end. Not like theres any shortage of variance from that aspect. Variances enough in watching HD over the years that if something is ho hum it's ho hum and if it's killer it's killer to the point where no matter the resolution or what the STB is set to at a particular moment, it wouldnt make any appreciable difference in my mind.

I too leave it set to 1080i, except when I watch 24 on Fox. That's my only favorite show and it makes me feel special when I watch it in 720p

Like others have mentioned, all the dish hd receivers do a great job of converting 720p to 1080i. However, they do a horrible job of converting 1080i to 720p.
Yeah, 1080i signals take on a "grainy" look when you let the 942 do the 720p downconvert.

Not sure about the 622, but the 942 has a nasty habit of locking up and rebooting about half the time you try and change output resolution. Those few seconds and a couple of button presses turn into 3 minutes of lost time.
