To encode a RMVB to DIVX/XVID

I am using Winavi 7.7

1.) I found some codec/encoder, one is xvid mpeg-4 codec and one is zjmedia mpeg-4 codec in xvid.
Which one is better?

2.) Or better still, which program can have the fastest/better "rmvb to DVIX/XVID" conversion that winavi?

3.) When i use winavi 8.0. I had an error while starting to convert a video - "Division by zero", then it hangs. Any solution?

 

Winavi is a pretty fast converter. If you download DIvx or ffmpeg, you will be able to chose other codecs for encoding.

You can also give "Any Video Converter" a try. There is a free version:

I use WinAvi Video Converter to concert files but all i get is message,
"OutDir Can Not Include _" then it hangs. every video i tried to convert to any format i get same message. what is the problem?
