[ConvertXtoDVD] Video is off

I convert and the sound & sub is accurate but the video is off.

I took a screenshot of the details:

Every mkv file I load says frame rate is 23.98 & the audio 29.97 FPS. Why is that? Is that the problem? How do I fix this?

There is no mention on audio FPS.
Update to latest version and try again.

Thanks, I updated and it seems to have fixed the problem.

I thought I had the latest version, I should have checked.
