Within CS3 I want to export a 23.976 DV AVI for use in Encore. I am working with 23.976 frame Cineform HD AVI's. The problem occurs when I try to export to a 23.976 DV file. After exporting, the properties of the clip say 29.97. I want a 24p file to author with.

Premiere Pro CS3
Aspect HD 5.05
Encore 2.0

DV Compressor: 24p(advanced)
frame rate: 23.976
field: lower field first
pixel aspect:1.2

could it be your pixel aspect? I usually set mine to square, and the exports look great. but then again, I'm not using cineform, and shooting 720p.
