I got one last week, and it is working just fine. So far, I've only used Fujifilm DVD-R media (TYG02) and have burned several movies with it. All of them have played perfectly in my DVD player. I did make one coaster on my very first attempt, but I think it was probably user error rather than the drive
I checked several of my burns with Nero CD Speed (KProbe crashes my system...). The quality ranking has always been in the mid-90's, with PI errors no higher than 38 max and PI failures no higher than 2 max.
So far, I've used two programs to burn: DVD Decrypter and Nero 6 Express. I also used Alcohol 120% to burn one CD-R with it -- it was real fast and a perfect burn.
