I have an ISO file that I downloaded. The file is about 4.2 GB. I'd used DVD Decrypter and the error that I got is: "Cannot open file:" w/ the file name and a second line saying: "Reason: The filename,directory name, or volume label syntax is incorrect" When I use Nero 6 Ultra Edition, I choose Nero Burning ROM, DVD, DVD-ROM ISO, NEW, add the ISO file to the compilation, and get an error: "The file is larger than 2 GB and therefore cannot be stored in an ISO file system. Please use the UDF system to stored such large file." When I choose the DVD-ROM UDF option,Nero just burn the DVD image. Therefore I cannot watch the movie. Any help is greatly appreciated!
