I've been a big fan of Sony's DVD+R and DVD-R media for years and use it for a lot of my personal stuff. I picked up a spindle of their DVD+R discs at Best Buy today and was surprised that the MID was RITEK F16.
Sigh.. It's getting harder and harder to get good recordable media. Everyone seems to be using Ritek or CMC and the quality varies so much from spindle to spindle that its a crap shoot. I guess I'll have to try to hunt down some SONY D21 discs before they're all gone.
