Hi, back in the early days of CDR media, we used to consider some drives even incompatible with certain colors. It was a long time ago so if I recall the dark blue ones were the best choose and the silver the worst. Where did your elephant memory recalled that ?? It should have remained in a small drawer in the smallest corner of your brain. Am not sure though brands ( HP, TDK,...) have to do with it, I used to use many of them , just the color.
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.

Sometimes the color of the media screws up the wavelength of the reflected laser so it doesn't register correctly. We've had problems with that using cheap DVD-Rs (we stick with TDK or HP now). It was a huge problem back in the early days of CD-R media.
