Can't burn 16x on liteon sohw 1693s

I’ve tried upgrading firmware and lowering write speed but still am experiencing burn errors while using 16x dvd’s on my sohw 1693s. Tried using memorex and sony disks.

Any help appreciated!


those arent the greatest disks. and also the 1693s likes + (plus) discs a little better than the - (minus) discs.

were u using plus or minus?
