Actually, Premiere Pro (1.5) does NOT work well with this. If you edit in D1 (486), the media encoder will not retain crop settings for MPEG2 encoding, and you get an error every time you try to do the 2/4 line crop thing, and the DVD encoding fails. Ran into it last month. Posted a bug report to Adobe, and no response. Which I have to say has become typical of Adobe of late.
Sorry to be such a downer,
Jeff
