FWIW, After a couple weeks of tweaking, I finally have a very good SDTV picture on my 50" DLP. I run Cox digital cable, via the S-Video connection from the STB on my HL-S5086W, for reference.
What I have discovered is that contrast and color need to be backed waaaayy down to get the most out of SD programming. I found this across the board on 3 TV's in my house when I looked at the relation of the DVE calibrated DVD setting vs the settings I ended up with for television.
Just an FYI, you can get an outstanding SDTV picture with some patience/experimentation. I did find the S-Video out performed far better (especially with picture detail) than RF out from the STB---I know, it should be a no-brainer.
Try dropping contrast and color way down, and go from there.
