Good reply on all but the Hitachi upconversion. It does indeed convert everything to 1080i. If you don't believe me, check out the specs here:

Many other posts on this site and others have said the same. I did my research before buying. Hitachi also has some marketing hype about a "VirtualHD 1080p Video Processor." I read a technical description about that feature on an independent site; it doesn't actually works like true progressive scan. I will say, however, that I rarely notice interlacing artifacts. (Of course, I'm easily distracted by plot and sound effects, so maybe it's just me.)
I agree completely with you about the varying quality of DVDs. I place the Chinese flick "Heroes" at the low end and the recent "The Island" at the high end of the picture quality scale. And I appreciate your clarification of the reasons for varying picture quality from broadcast and DVD sources.
I rather supect that some program material on the Dish HD channels -- especially movies -- is really upconverted DVD quality. Some programs have the HD tag at the end of their description, and others don't. Any insights there?
