I agree that the odd and even lines are "spliced" together to create an "eventual" 30 fields per second, but I was taught that the DVX records to tape a field of odd lines for the first field, then a fraction of a second later it goes back to the top and records the evens. Thus you have 2 "moments in time" if you will, to eventually be spliced to get one full field, resulting in 60 moments in time per second for 60i. This is why you get twice the "moments" to work with in a 40% slowdown when in a 24p timeline as compared to 30p with its 20% slowdown. So the NLE has all these unique fields sequencially available to work with. But each one of these fields is "unfinished" with half of its lines missing, which the NLE has to interpolate or "guess to fill in the gaps with fake image info" to produce full fields. This is why 60i slomo results in softness compared to slowing down progressive "finished" full fields.

^As far as I know this is correct.
Also, if you are using Premiere CS4 you can right-click on your clips and select "Interpret Footage" which allows you to change the framerate without having to export (not sure if this works with CS3 as well).
