If you want to see what standard def is supposed to look like (on any TV), set your HD DVR or receiver to standard 4:3 TV Ratio and video to crop. Then output to 480i and tune to an HD channel. There you go. That's about as good as it gets. No doubt there's a slight improvement on some standard def channels that use HD sources (such as NASA in MPEG 4), but also we shouldn't forget that using an HD source for the above experiment (or a DVD for that matter) is kind of "cheating" since you're actually getting a horizontal res of 720 vs the standard 640. Suffice it to say, nearly all standard-def programming (including PPV) on D* is lousy PQ and is easily compared with VHS.
