Thanx for the replies. DVDinfo Pro, Binflash GUI and Nero CD - DVD Speed all say booktype set to DVD-ROM, however DVD Decrypter still says booktype is DVD+R!! Burnt disc regardless and it will play on my Wharfedale M1 which wouldn't previously play dvd+r's. However, sometimes when i load the disc it will return an unknown disc error. What i need to know is, is DVD Decrypter functioning properly or do other people have similar problems when loading dvd+r's where their set top players wouldn't previously play them until they changed the booktype? Hope this makes sense, just trying to narrow down the cause of the unknown disc error.
