What format are the movies in now? Are they regular dvd video on disks?
If they are just plain old dvds, you can use most any decryption/ripper program to get them from the disk to the hard drive, depending on the type of protection they may have.
I’d try DVDShrink or DVDDecrypter first. If you use Shrink, you don’t have to use any compression if you don’t want it. You can find both programs at www.mrbass.org
If there is a newer protection that they cannot handle, you could try DVDFab HD Decrypter. http://www.dvdfab.com/free.htm
All of these programs are free to use.
