Sorry to hear your duplicator is not functioning properly.
In order to help you as quickly as possible, could you let me know: when this problem started and whether this applies to all 10 discs in the batch or just some?

Is your DVD master disc finalised and playable in domestic DVD player?

Have you recently started using a different type of media?

Are you able to duplicate CDs ok.

Best wishes

for some reason VERBATIM (yes really) sometimes has this problem - please if possible try alternative media to see if there is a prbolem here also. Have you tried reducing the bURN speed on the duplicator to help prevent underruns. THe disc might be rated at a speed higher than the duplicator can attain set in MAX speed. THe machine I bet just hangs there..... refusing to burn - this problem we ONLY see with verbatim. Pls try another brand of media so we can be sure where the problem is in order to find a solution. Kind regards.

Has this problem been resolved? Kind regards.
