Bill: I've been shooting in 30p mode because I think the slow motion looks better. If you watch Delta Sessions closely it's easy to see the footage shot with the DVX vs the footage from Arun's and Bryan's GL2's. Look closely at Schwenne's segment on the Delta where we go from the side to behind the boat shots and you should be able to see the slightly more washed out color & resolution of the GL2. I don't tweak the Cine Gamma settings because nothing we're doing will end up on film. The DVX has a warmer more filmic look than the PD150 and looks sharper to me (probably because the DVX records more information on each frame in progressive mode than an interlaced DV cam of the same chip size can). PD150 video does look a bit smoother though because it is interlaced.
The DVX handles like a dream compared to any other cam I have owned, it's hard to describe exactly why, they just have a great balance/layout/controls. The new 100a model has fixed the only complaints I had about the cam (the viewfinder and no one touch AF in 24p/30p modes) I don't care for B&W viewfinders like the PD150 has but they are easier to focus. Panasonic has added a setting on the 100a VF that gives you the sharpness level of B&W but in color so I can't wait to see that. Bryan has the new 100a and shot a lot of his new vid "Untouchable Sound" in 24p so it will be interesting to see how it looks on DVD.
The new PD170 really doesn't address the needs of the indie filmmakers and it appears Sony is aiming this model at the ENG crowd. The DVX has literally taken over that whole Indie market. The rumored Canon XL2 may bite into that somewhat but Canon can't take a crap video wise without Sony's blessing so we'll see.
The bottom line is you can make DVX video look anyway you want with all those (heretofore) hi end gamma, contrast and knee settings built into the cam.
