Hi,
Yes there is a program to copy your DVDs to your Hardisk. Download DVD shrink. Its great, you can even set it to automatically compress a DVD so it can fit into a DVDr for backups in the future. Also if you have Nero, you can make a backup copy of your DVD to a DVDr. If you have different region DVDs like Region1 you can also use DVD shrink with this, but you will need a program to remove the region lock, download anydvd, or DVDidle. I think regionkiller works to this is freeware unlike anydvd and dvdidle.
