Libdvdcss cracks the encryption (when present) by brute force in software. In my experience that can take a while, although I think there's some caching ability for next time you play the same disc (though I rip such discs so I don't have to bother with it again). I think I also had it fail once but that might have been a scratched disc. Generally I still try to avoid DVDs from other regions, although DVDs marked Region 2 only are often really Region 2/4 so play fine here in Aus. -- __ __ #_ < |\| |< _#
