WinRAR will compress an AVI to approx. ~98% of its size (it is already heavily compressed). Most file compression software will attempt to replace repeated information with a 'shortform'. In this way, any document can be easily reduced in size... However, you can see why this will not work well with a Movie (no repeated info). So basically an XviD AVI is about as small as it is going to get, Regards
How about a program that can reduce resolution of the Xvid Avi Files? that way the file sizes are lower.
