I tried many tools for converting rmvb/rm to mpeg4(Divx or xvid),this one is the best!
the speed is very fast,It take me about 10 ~20mins to covert a movie (rmvb to Divx).
WisMencoder 2.1.1.0
This is a free software and you can download it from http://www.mzys.cn/
or http://dl.pconline.com.cn/html_2/1/1...41%26pn=0.html
but it's Chinese vertion, I am searching English Vertion.
From the website I know there will be multi-language vertion after a while.
