Premiere 6.0
I was fortunate enough to have access, until recently, to an edit bay that featured Adobe Premiere 6.0. That software has a couple of techniques that can be used to make DV look more like film. 1) Deinterlace Frames - allows you to clean up the frames, but you can still tell it's DV. 2) Flicker Removal - primarily used for taking the "flicker" out of slo-moed shots, it can also be used on normal speed shots with an end result that mimicks film. The problem is that if the video is even slightly "hot", a whole lot of pixel glitches can appear. If you have a dark film, this technique is great, and it really looks a lot like film.
Other than that, I don't have a lot of info. Plus, you might be able to find out some more stuff about these techniques that I don't know.
A friend of mine uses Adobe After Effects, and he says that he can make DV look like 35 mm. Unfortunately, I've never seen this done.
Hope this helps.
