Hi and thanks for your reply, I am not sure how to finalise the disks using DVD Shrink 3.2. There is nothing in the settings it just uses NERO to burn the disks.
Re the media it is a make I have always used with no previous problem Sun Vision Gold top.
My burner is OPTIARC seem okay Sata
Can you recommend a good all in one piece of software for burning and do you think this might be my issue with DVD Shrink I know this is an old programme?
