As a matter of fact, XviD is not a video format – you will not see a file with the file name extension .xvid. It is a free program published in the GNU General Public License which based on the MPEG-4 format. And XviD produces greater performance and a lot more options compared to DivX, but this is also the reason which makes XviD a little bit more difficult to master for the general XviD players.
- 'When I am trying to play a number of movies XviD files downloaded from the internet the program (Windows Media Player, BS Player, DivX player) all crash. What is happening?'
