i burned a .mds file onto a disc and then tried to get another one but dvd decrypter would not let me, but there is enough room for two. Are there any programs that would let me do this?
mds file A MDS file is a small meta file that contains description information about the associated ISO. It is not an ISO file nor can a MDS file be converted into a ISO. You must have the ISO; however, you can usually have an ISO without a MDS. So, no need to convert, just play the ISO.
