I am a religous user of Taiyo Yuden and Verbatim media. I have an LG GSA 4120b (yes, it's an LG, but this model has burnt flawlessly for me - it is however LG's first Super Mulit drive; they seems to have gone down hill lol), and I burn Verbatim 16x Dvd+R disks at anywhere from 4-12x. They code out as YUDEN000T03 (Taiyo Yuden BTW), which is an added bonus; Verbatim disks, that code as TY! I also only use Dvd+R disks, as I like to bitsett/booktype my disks to -ROM for better compatability. Even though -R came out first, that's just how I do it. Each to their own.
The only other media I use is RicohJPN - not *the best*, but it is OK media for less important backups, IMO.
