Hearty thanks cwrightthruya for that advice. I actually ended up proceeding slightly differently, using Nero Recode (and with 'AnyDVD' running in the background). Thus I was able to burn to a folder of selected items from the original disc (other items had been Disabled), using Nero Recode's own burning procedure. Then, still using Nero Recode, I burned the items onto a blank DVD+RW. The latter wasn't one of the brands recommended by you, but I HAVE noted your advice!
Now, anyone, a question. Since using Nero Recode, every time I insert a new movie disc into my laptop, Nero Recode opens up unbidden. How can I stop it doing that, please?
Thanks - Ken52
