I've burned a couple hundred now, and I've had great luck with Verbatim, both DVD+R and DVD-R's. The 16x Verbatims I've used lately have had 100% good burns. The 8X and 4x Verbatims have not quite been as good, but not bad, they almost always fail just after the burn begins, unlike the 200 Ritek G03 disks I bought back in January. In the one "beehive" I will hit 2 or 3 coasters in a row, and then 4 or 5 good burns, it was a little better on the other one, from another run. Worst thing is, most of the time they fail at 90% done and sometimes fail during closing. I gave a chunk of them to a friend to try in his Pioneer burner and they puked 6 out of the 10 I gave him.
They are almost gone, thankfully.
Now I just have to use up the 200 Ritek CDR's I bought at the same time. They aren't a whole lot better.
I've had great luck with Fuji's. If the DVD's hold up like their VHS tapes, they will outlive me by far. I have some stuff I taped 25 years ago, and only the Fuji tapes play well at all without playing them several times to "loosen them up" before you can stand to watch them. No other brand of tape is as stable as Fuji, not even close. Time will tell on the DVD+R's
