Is .rmvb Files Better Than .avi Files?

Is .rmvb files better than .avi files?

Cos .rmvb seem to be smaller. 45 minutes of excellent quality is only 150MB.
Making an average movie 300 -- 400MB.

Are they the future?

they will have to fight me and kvcd :angry:

j/k I really like both but most rmvb have foreign subs at the bottom, I don't like that but other wise great compression

.avi is better I think.

.rmvb is just realmedia

well sort of
its real media Variable bitrate
and if you haven't seen one yet be prepared to be shocked at the quality, I was if that tells you anything
