convert rmvb to mpeg or avi

how do i convert rmvb to either mpeg or avi file?

what software should i use?

thanks in advance

Try this for size....

Super RM to AVI DVD VCD SVCD MPEG Converter 1.18

TEk

Not much cheaper,but another option: http://www.boilsoft.com/buy.html

are there any converter that converts the whole video without putting watermark?
it's also fine if the converter splits the video into many clips, as long as it converts the whole video

thanks
