|Just to clear things up a little. AVI is not a format, it is a container and can be used for any one of a dozen or so formats. This is the problem with AVI as you never know what format you are getting if you download a video with an AVI extention. This could be why your friends DVD player isn't working with a video that worked on a different player. His current player may not have the codec needed to play that particular video format.|
"in 10 or 20 years from now, they may have a new video format again and then FLV and MP4 may become obsolete"
Yes, that is most likely. Many formats used back in the days of Windows 95/98 are obsolete. As new technologies come out and computing devices become faster, newer more resource demanding but more efficient codecs are being created.
