I am ready to burn the first year of a five year garden project to a DVD. I would like to
(1)overwrite an existing DVD and
(2) need to know how to add further years to the DVD once I have completed editing them.
The DVDs are RW +/- and I have done my editing using WMM.
Thank you in advance to anyone who can help with this very basic problem - in fact it's so basic I cannot find the answer to it anywhere.
