I'm also using rarlab its basically the best thing after zip which comes with windows 7.
its strange that compression works best for none media files, for example games can be compressed from 5 gb into 2 gb , software can be compressed from 1gb into 700mb etc
the same does not seem to work on media files such as video or audio, but we already have many encoding formats h264,vp8 etc theora hmm maybe thats why.
