Ah, Kostas! Yes, I dusted the cobwebs from the deepest part of my memory
to find that bit about the color of the CD-Rs, but color can still play
a part in DVD compatibility. DVD drives are just as sensitive to the
laser color and reflectivity of the disk. In addition, there are DVD
drives that are compatible with DVD-R(W) media but NOT DVD+R(W) media
and vice versa.

As far as branding is concerned, there are a limited number of makers of
the media and that product is generally purchased and rebranded by the
major players. However, I find that going with one of the "big labels"
gives one a better chance at getting reliable media. I've had very good
luck compatibility-wise with TDK's DVD-R media and both of HP's DVD-R
and DVD+R. Keep in mind we have some pretty funky old systems laying
about here and it can be a challenge to get media to read on some of
them.
