I hate the quality of SD at 1080i on my 942 compared to my old D* UltimateTV box upscaled by my HDTV. Every time I've complained about this issue, it gets dismissed on these forums, but my SD content looks like analog cable (or a low band internet stream) on my 942, so I have a tendency to watch nothing but my HD line-up. Actually, any improvements at all aside from a few new feeds? I've poured through many threads here and I really can't decide whether the upgrade is worth the hassle, regardless of cost. How long is it going to be before the MPEG-4 bandwidth advantage is realized in terms of quality for existing MPEG-2 feeds? I'd love to have Universal HD back (from voom), but considering that I have flawless OTA HD, is there any real advantage with the 622 (predicted within, say 6 mos)? Lastly, does the 622 do anything but "partial zoom" for 4:3 content? A more advanced scaling mode seems way past due.
