And yet I do, as is evident in the picture I posted.

Broken link for me. :(

Premiere has a better Interpret Footage dialog. You can create and name a new 23.976 sequence, import the DV file, interpret as 23.976 and progressive, and drag the file to your sequence. Then save project and import the project into AE. The resulting sequence(s) will play back correctly.

If you're still getting combing after this, then it's baked into the source. Try upper/lower field. If neither works or only partially works, it's maybe telecine; in AE's Interpret Footage try Guess 24Pa Pulldown.

Edit: clarity.
