Playing mp4 file from converted DVD (.vob)

I converted a .vob to .mp4 with Movadi after trying to play the DVD on my desktop computer and sharing the screen which led to it freezing 15 minutes in. So, after reading up on it, I converted to DVD file to a .mp4 file.

When I tried to play the .mp4 file via Advanced Sharing Video, Zoom said it didn't recognize the file. Why is that?

I've converted it now to a .mov file which Zoom recognizes. However, for some reason both the .mp4 and .mov files have audio and video that aren't synced.
