Its not just an issue of the quality of the media. Compatibility with your drive is just as important. The sad thing is, anymore, most media is average at best and compatibility is poor between many drives and medias. If I had to make a guess why, I would say that prices have gotten so rock bottom, it no longer cost effective to put the time and resources into strong firmware development (which would provide good compatibility). Media that was often considered average in the 4x and 8x days is now considered good quality compared to most 16x medias too.
Like jamescooley1 said, ty and verbatim are your best bets. I have had good luck with sony too but it depends on the drive.
I would recommend learning to error scan your disks as it is the only way to tell if they are burning well (even top quality media may burn poorly if the drive doesn't support it well). What kind of burner do you have?
