I downloaded a ratDVD file and wanted to convert it into DVD files. But for some reason, after waiting 6 hr of my life, it turns out that I only got a single UNKNOWN file converted. This unknown file can be played through WM10 and Nero Showtime, but the problem is, how can I burn it? It doesn't seem to be an ISO file because ISO programs and Nero Recode did not recognize the unknown file. Someone please help?!
