Okay, I have the new Sony DRU500A that can do - and + running XP, dont know if it matters. i downloaded DVD decrypter and and ripped a DVD to my harddrive (it created two files one an large file: .iso and another a small file: .mds. when i went to write the dvd i used the .iso file. i have tried burning this twice, once with a cheap dvd-r and once with an expensive hp dvd+r the -r seemed like it did nothing, decrypter doesnt read anything on the disc post burn. the plus looks like it burned something but decrypter only says it only has 2,048 bytes on it (but it took 30 minutes to burn!) plus when i put the +r in the drive and try to open my dvd player it says the disc is of a format not supported. when i burn the dvds it says dvd successfully burned both times. a little not of info, my aspi file is in the nero directory not the windows system 32 directory, does this matter? i am trying to burn a dvd less that 4.3. please write with any tips or ideas. i dont know what im doing wrong! im about to return the writer!
