When I'm using DVD Decrypter, it's burns fine in about 10 minutes. When I choose the option to ISO write, and enter in my blank DVD, there are two files, a .ISO file and a .MDS file. I click on the .ISO file and I get an error stating "You should have selected the MDS file and not this one. I'll do it for you automatically this time, but don't do it again!" What does this mean? Any help out there would greatly be appreciated.
