A lot of people I've seen seem to prefer anydvd, but I've never gotten it to run, so I use DVD Region+CSS free.
this is a old topic posted many times here at aftredawn, i use DVD Region+CSS Free and have had great luck with the program, the only downfall with it is , it dose not have a ripper, like anydvd, a lot people here use anydvd, and as far as better, to each his or her own.
