My DVD burner is under a year old and I normally use nero to burn DVDs. I have burnt both types on this burner, and am halfway through my stack of DVDs so I am sure there is no problem with my burner or discs which I use for my photography business, so I try to get the best. Definitely DVDs. I get to the ISO stage, so will have to use another piece of software to burn it. When I buy the next stack I will ensure I get the right type. (found the label - current batch is DVD+R) thanks for your advice. - I have learnt not to burn at more than 8x. Ironically the only DVD I have managed to burn was at 18x. But it only worked the once, I only tried out of desperation
