Well in the UK its not illegal to copy DVD's for personal use and for backup purposes.
I use DVDshrink which will rip most DVD's ... although more and more have additional CSS encryption and some are even muddling up the DVD structure so even DVD Decrypter will not work.
For those i use anydvd to remove all the encryption and DVD Shrink to Rip to disk.
Then i use manage collection and mymovies plugin for MCE.
So far i have ripped over 100
