When DSLR video's hit the market, the companies weren't ready for it. Although FCP has had some plugins designed and some Compression settings to convert them to an editable format, I think Adobe is setting the bar. Jason Levine shows off some of the new Native DSLR Editing on Adobe CS5. I like it, I think i'm going CS5 just for the editing ability.

I have Premiere Pro CS4 and it has worked nativly and very smoothly so far with my T2i footage. It just doesn't have a section for DSLR footage in the sequence start up menu thing.
