I'm with Rick. In most cases, you'll lose half the vertical resolution by deinterlacing interlaced footage. To deinterlace correctly and save as much vertical resolution as possible, you'll be adding a ton of setup time and rendering time. We haven't even talked about interpolating from 30 FPS to 24. For a feature this could all amount to loads of added post-production time. By the time your feature is done, you'll be so sick of deinterlacing you'll have wished you would have shot on the smaller CCD size of the DVX100!
In cases of fast motion, the progressive frame can sometimes encode a better looking image in progressive than interlaced, so you'd have that going for you too.
And if you do shoot on the DVX100 and you want lossless media transfer to stay in 24p, make sure to shoot in 24pA (Advanced) mode versus 24pS (Standard).
And if you're really lucky and have extra budget, rent a lens adapter (like the RedRock Micro unit or P+S Technik) to mount fast F-stop lenses for some serious narrow depth of field. Shot correctly, it can deliver some of the most incredible stuff you can lay your eyeballs on! You'll swear it's 35mm!!!
Good luck!
