DVD re-writer does not recognise it as a DVD :-(

Now you've really confused me. You say you gave the shiny side a wipe
and then the "label/data" side - the label and data sides are
opposite. Is there any chance that your friend's disks don't match the
"colours" you're used to. E.g. most DVD blanks have a blue or purple
hue on the data side but I've seen some which are silver and have
occasionally been confused as to which is the label side and which is
the data side of the disk (particularly in artificial light).

Sorry for any confusion.

The data side of the disk is immediately under the label, so that puts
it on the label side. The data, as you say, is read and written from the
shiny side, but what got me was that I could damage a DVD by wiping the
label/data side with isopropal alcohol.

Over the years (15+ or more), I have had disks of all types of colour,
or none and never had this sort of problem before.

Many thanks for your help. I have been told that he can't finalise his
disks with his DVD recorder today. Either that, of was saying that he
couldn't erase a DVD RW on that machine. I did say to him that his
computer would erase it.
