LoL @ topic swaying into pron talk.

Anyway, the only method to fit quantity into a media at present is to compromise on quality until there's a superior compression method in the future.
Usually, it is just a matter of expanding the media i.e. dvd vs bluray OR improving compression techniques with minimal quality loss e.g. avi vs rmvb.
although I've not used any before, I believe there are a couple of compression softwares available to fit more files into current mainstream media i.e. dvd/dvd DL.
