[MacDV] 23.98 fps when using Cinematize or DVDxDV

[whoisquilty]

Hello -

I keep getting Quicktime files with 23.98 FPS when I convert a DVD to
MOV with both Cinematize and DVDxDV. I'm trying to create a NTSC file
from the DVD. The frame is sized to 720x480. But the frame rate always
comes out to 23.98. I ripped the files using Mac The Ripper 2.6.6.

Any ideas what would cause this?

Jer
