MCC004 or MCC 03RG20 for 3550?

Which one is better ?

Verbatim dvd+r 16x (MCC004) or dvd-r (MCC 03RG20) ?

Currently using original firmware 1.06

Short answer:

Verbatim DVD+R 16x (MCC 004) is better and you can safely burn it at 16x.
Verbatim DVD-R 16x (MCC 03RG20) can be just as good if you burn it at 8x.

The answer may change if you get a particularly good or bad batch with one or the other of these two media.

Thanx, will get 25 pack each.
