Hey, I'm new here. Please don't eat me if I ask stupid questions, as I'm quite sure I will.

Anyway, I have Premiere Elements 3.0 and I'm trying to start a new project. All my source videos for this project are from NTSC DVDs with framerate 23.97 fps. I want my project settings to match that, so I tried to create a custom preset based off of "DV NTSC Widescreen". Only problem is that it won't let me change the timebase to anything other than 29.97 fps.

Is it possible to somehow change the timebase to 23.97 fps?

Oh, and would I need to change "Display Format" also? The only options there are "30 fps Drop-Frame timecode", "30 fps Non Drop-Frame timecode", and "Frames".
