Actually, I think ALL the players you mentioned will give you fine picture really. however, you may want to look into players, such as the Pioneers newer units and Theta's pieces, which will pass a pure, untruncated, 24/96 digital signal for the audio! I'm sure many will say that, for 16/44 dvd's, it doesn't matter if your digital out of the player down converts the signal to 16/44(most players do!). I've found that the sound seems much better with players that pass 24/96 digitally, and doesn't do any down conversion, then up conversion in the processing chain!!!
However, MSB will upgrade any player to pass a 24/96 or even 24/192 pure digital signal out of that out put!...so you may want to consider having a player moded for that if you go other ways.
Also, may I strongly suggest, that if you want to improve your picture situation, that you sell the Mits and get a good DLP and front screen projector set up instead!!! You'll get a much bigger and better picture, which you can sit much much closer to proportionately! The reason?...it's the dreaded lenticular screen on all big screens that keeps you from getting closer...no matter what DVD player you use! Even with high Def 1080i, you still can't get past the limitations of the lenticular line struction inherant in your TV. a good DLP with wall screen would have no such limitation, and you could easily get a trememdously good picture on a 100-110" screen in a medium/modest size room!
