Confused

Hello Forum,
I am using dvd nextcopy ver. 4.5.0.5. and any dvd ver. 7.3.2.0.
my operating sys is windows7 home premium
On some dvd’s that I want a backup copy I only get around 740mb
burn on my backup copy. I wash the source dvd to remove any dirt or
grease. Do you have any ideas why this happens ??.:confused:

You need to probably use the NeXt Tech Updater in the program.

Thank you Dr. Who for your reply. I do not want to sound stupid but how do I find "next tech updater in the program. I am not very knowledgeable on these things. If you could guide me through the process I would be very thankful.

The best way is to use the manual on the providers site. It has been over a year since I last tried it but I no no longer have it installed.
