I am just making some experiences with different media, mainly normal 4x DVD+R and DVD-R media (since I still have a lot of this stuff which I wanna use first before buying new media), and up to now, I am quite disappointed of media compatibility. For example. Optodisc 4x DVD-R media fails to read at about half the disc length in multiple drives, same with Ritek DVD+R 4x.
Furthermore, I found out that burning results decrease as this drive becomes quite hot in permanent operation. I already managed to burn an unreadable Taiyo Yuden 4x DVD+R (which normally works flawlessly with that drive), after a long reading session after which the drive seemed to have a very high temperature.
I am sill unsure whether to return that drive, or whether there is any solution to my problems. Firmware is A102, which is the original firmware.
Maybe somebody can give me any hint?
Thanx & cu,
