Have a clip that avicodec says is 23,976 fps

So I fire up the new TmpGenc 3.0 Express and load the svcd NTSC FILM template. I look at the Encode settings, and it says it's going to make a 23.976 mpeg movie. I encode a little bit and avicodec reports the mpg as being 29.970 fps. I found this out because vcdeasy warns me that this is not according to standards.

If I use an older version of tmpgenc and the ntsc film template, avicodec reports as 23.976 as it should be. And vcdeasy is not complaining.

Whats is going on ?
