Movie edit issue

[jk4u]

I recently installed your program Freemake Video converter 4.1.1.2. I have
following observations:
1. I made a movie clip (avi file) from a movie video(avi file) through
Avidemux. The movie clip is not playing in Divx player but playing in VLC
media player. How ever the movie video was playable in Divx Player. Further
I tried to resolve this issue by again converting the video clip to avi
file through Freemake then initially your software became slow to
operate, and the size of clip went from 56 mb to 12500 mb (as estimated  by Freemake) . I did not complete the conversion.And same happen while converting clip to mp4 format.
We appreciate your valuable comment on the issue.
