I used DVD Decrypter to copy a movie to my HD. After I ejected the original DVD and I had a power drop and my system rebooted. I opened up decrypter to continue the burning of the movie to another DVD and as was following the directions on the After Dawn Web page (about using the DVD Decrypter)...something didn't make sense to me. I have two files on my HD a very large one 3.5GB with a suffix of .ISO. I have another small file with the suffix .MDS. The directions on the Webpage talk about a suffix of .DVD being copied..and it leaves me with the impression that there is only supposed to be one file for copy. I have those two. Before I do something really stupid and ruin a DVD-R...can someone please explain why I have two files..and if I need to burn both of them to the DVD...how do I do that? It appears that I can select one file or the other...or am I missing something? Hate to sound like such a dummy..but I've wasted too many CD-R's in the past..and do not want to do the same with DVD-R's now. Thanks for any responses.
