Ok, seems that everyone has problems with these drivers. First of all my spec:
MSI K7N2 ILSR-nforce 2 chipset
Athlon XP 3000+
512 RAM DDR 400Mhz
LTN 526S-LTR52327S, SD616Q-DVDRW SOHW812S.
I never used MS drivers. But i remember the first drivers of nvidia that i had installed i had problems with some cdr's.
After i installed IDE driver 3.66.
3 Days ago i tried the new 4.12 driver but i couldn't write with my dvd-r as it has been losing its buffer all the time. At the begining i thought that the problem was by my dvdr. At second thought i disconnect tha samsung dvd reader as it was at the same ide.
Finally was the drivers! For now on i 'll use the v3.66 drivers, i had no problem with those..
Hope to help..
