all the dvds here do not have copy protection thus it is not necessary to use dvd decrypter.

just drag and drop the VIDEO_TS folder to your computer, generate md5 checksums from the dvd you just copies from, then save these checksums to your computer and test them against what was copied to your hd. then if you want to burn another dvd from the verified files on your computer, burn it then generate checksums from that new disc and then run them against the files on your hd. so long as they keep matching up the extraction and copy are exact. it is a little different than audio cdr in this way.
