Hmm, I got the same problem with the GSA4120. Don't know what it is. The burns are fine and I am
using quality media. The reads, compares, and verifications are fine. Data integrity is fine.
I use MCC03 and RicohR01 DVD+R 4x and RicohW11 DVD+RW 4x. Then I try to burn the same data to DVD-R and DVD-RW
and the problem does not occur. Just burns on DVD+ media, with or without booktype.
I just notice this problem recently. All my old burns when I got the burner August 04 never did this
even when tested today. So it is something in the recent burns which affect + media.
Firmware is A115. Anybody got the same problem?
So I ask you folks whether full stroke performance of 1.5 - 2.0 seconds really matter all that much,
even though I know it should be around 250ms the most.
At this point, I don't know whether to claim warranty or not.
