Converted PAL to NTSC and some questions

The video stutters now and I guess it is the frame rate difference right? Is there any way around this? I used VOB Blanker to do the video conversion which was easy to do and I also used convertx2dvd to do another. The convertx2dvd had jitter real bad in the video so I didn’t bother keeping that copy.

I don’t know if you have TMPGenc Plus, but here is a guide for using it and dgpulldown to convert PAL to NTSC:

Seems pretty simple, though there are certainly other tools for demuxing/remuxing the video and audio.
