Re: DVD Upconversion Questions
1) How do you have the two connected? Depending on the connection, either the TV or the DVD player may be doing the upconversion.

2) "Up conversion" (we called it "line multiplying" in the old laserdisc days

is, of course, really a bit of an illusion. Neither a player nor a TV can add detail that isn't there in the source material. One or both can de-interlace an interlaced signal and then apply complicated algorithms to
guess what the "missing" lines and pixels would contain - based on adjacent pixels - and try to fill them in as best it can. How good a job it can do with this is based, in part, on how good the source material is.
I have a Sony DVD player that upconverts over component but not over HDMI, and a (720p) JVC LCoS that scales all inputs to its native resolution if necessary. I have both component cables and HDMI connecting the two, and I can't see a difference between the set's built-in scaler and the player's upconversion. I
can see a big difference in how different DVDs look. (Just as I can see big differences in how standard def TV program material looks depending on the source material.) Some of my newer anamorphic widescreen DVDs look stunning. (I've been watching a lot of
CSI lately and the boxed sets look almost as good as the HD broadcasts.) Older stuff from poorer quality masters just looks OK. (OTOH a non-anamorphic, but well-mastered disc like
Streets of Fire looks better than it has any right to.)
I don't think I'd trade in either the TV or the player based on some discs not looking good. I
would play with the different connections to see which upconversion (if any) is better.
