Dup-dvd

[JaPule]

I have Dup-DVD and it is register. I've tried to burn Road Trip a couple time but failed. After reading the DVD for about 5 hours it starts burning it into the CD at 6X but had an error. It asked if I want to try to burn it again so i clicked yes. It burned fine into the CD and the movie plays fine for 30 min(that's all the CD could hold). I tried to continue to burn the second CD but it would start all over again and would not let me continue(I did not exit the program at all). The setting I have on is SVCD High Quality, NTSC, 725MB Size. Please help out if you can. Thank you.
