Without the actual error message, it's hard to say...
Of course, the first thing you should try, is burning at a slower speed. Just because it says 8X on the label, doesn't always mean it will burn reliably at 8X. Try 6X and even 4X.
I have this iso file and its a dvd and when I try to burn it to an dvd r I get an error. I used dvd santa and I got an error. I used alcohol 120 and I got an error. Discjuggler doesnt even start burning. Nero never works for me. I always have problems when trying to burn something to dvd r sometimes. The dvd r is Phillips Dvd r
and I burn at 8x speed and the disc says 1-8x. Whats the best way I can burn an iso without getting errors. I only get this problem when burning dvd r's
