Jumpy playback , fps?

Hi , Im relatively new to burning and have a question.

I live in England and when I try burning an AVI file to DVD which is 23fps the video seems to jump slightly every second or so.

Files with 25 fps seem to burn with no problem.

The problem is most films I have are 23 fps.

Is there an easy around this such as a setting I need to change or some software that will easily convert 23fps to 25fps ?

I am using Nero 7 Ultra with a lightscribe super multi drive.Ive already tried burning at reduced speed but the problem is the same.

Thanks in advance.

You need an NTSC capable player/TV.
