I have been using an EMPREX 8 speed DVD burner for some time and have found it to be OK. Using 4x disks it read these as 4x, but when I inserted an 8x disk it read this as 2x. A computer shop told me that my DVD burner needed a firmware upgrade. So I went on to click here as recommended by EMPREX and downloaded the relevent upgrade, result one dead DVD drive. Warning do not use these upgrades from this site. Yes I did follow the instructions correctly.
Thanks to all who replied. Fortunately I had a spare drive which I installed, this is the same model but manufactured six months later and must have the upgrade firmware as it reads 8x disks as 8. Regards
