What size is that iso file? If Nero and decrypter failed,then it probably is too large.
Anything over approximately 4.5 gigs will have to be reduced to fit on stand dvd recordable disc.
Try DVD Shrink :It's free and a very high quality program for reducing larger files or original dvds and compressing them to fit stand disc or dual layer.It uses Nero or DVD Decrypter to do the burning without having to open either of those 2 programs up manually.
Hey bevan, that program "easy dvd creator": Is that a roxio program?
I am not much of a DVD Decrypter user,DVD Shrink and Nero do just about everything along with AnyDVD running in the background for my backup movies.
Can you descibe your process of how you are trying to burn it and how far into the burning phase before the problems begin?
More info would be much appreciated so others can help get this problem solved.Pc spec,all dvd software if you left any out,burner model # and brand,and brand and format of media you are using.
