I have still problems with:
1) dvd-rws with mid code OPTODISCK001 branded B.O.S.
2) cd-rws with mid code LeadData branded LeadData
for 1) they are writeable with firmware 0043. That's why i'am still using 0043.
for 2) these rws were writeable with my previous 2 writers.
So there is still no improvement for me :sad:
I write my dvd-rs with mid code OPTODISCK001 branded B.O.S. @ 2x instead of 4x. I don't dare anymore to write them @ 4x.
