Both Verbatim 8x DVD-R and Verbatim Pastel are good in GSA-4163B.
But SEARCH, SEARCH, AND SEARCH for more information.

My 4163B gets better results with Verbatim +R media especially at higher speeds. Best to try + & - on yours and see what you prefer.
Verbatim 8x DVD-R (MCC 02RG20) seem to burn the best for me and 16x Verbatim (MCC004) for DVD+R media, their 8x DVD+R (MCC003) media doesnt burn as well (though the burns are still better than most other brands of media) as either of their other medias.
Ritek G05 (8x) media seems to be problematic for the 4163B as more often than not it will only burn at 6x (even if 8x is selected).
Flat out best, no question about it, TYG01. Close second is Verbatim MCC 02RG20.
MCC003 burns perfectly for me, every time. I must confess I haven’t used the Verbatim 8x -R or 16X +R media to compare, but it’s hard to see how it could get much better.
In general I get better results with +R on LG drives.
MCC004 @16x is the cat’s azz, YudenT02, MCC02RG20, TYG01, TYG02…
At rated speeds, you can’t lose with any of this media on the 4163…still use firmware A103…no reason for me to change (love this drive).
+R scans (next post for -R scans):
Scans (cont.)
1: TYG01, Fuji Branded @ 4x
2: TYG02, TY Hub Printable @ 8x
3: MCC02RG20, Hub Printable @ 8x
Can’t go wrong with any of those…
I’ve been out of MCC02RG20 for a bit now, gonna get some MCC03RG20 (16x) next to try.
