I'm using a DVI cable on a Sony KF-50WE610 (GWIII), and the 921 SD using "Normal" mode upconverted to 720p or 1080i is simply not as good as it should be... Which is to say that it is not as good as taking a 508 and hooking it up using an S-Video cable. It's watchable, but it's not as good.

I suspect that we are seeing an effect of the internal de-interlacer and scaler on the 921 being inferior to that on many of our TVs. It is possible that the analog outputs are not too well adjusted either; I have observed quite a bit of variation on the output levels of the various Dish receivers (versus VCRs and DVD players). For best possible results, you should probably watch SD in 480i on the DVI port, thus eliminating the analog effects. :( Oh wait, the 921 doesn't put 480i on the DVI port!!! :mad:

The next best trick is to record a test patterns from somewhere (I caught one by accident from a local station and HDNET puts up a poorly chosen color-bar in a weekly show) and adjust the TV settings accordingly. You can find instructions for adjustments using color bars in AVIA or Video Essentials DVDs or probably on the web. In my case, the svid output was significantly different than the output of my DVD player's svid. When adjusted the picture is markedly better.

Thank you for saying what I was trying to say in English.
