I use injet printable DVDs so I can label them. I've been using Verbatim Data Life Plus PN 94854 for what seems like a decade now. Burned thousands without a defect.
Dunno about other brands, but the defect % is high on some of them.
I would recommend a new archival disc by MDISC.
Has no dyes but uses a new type of surface that is like burning into stone.
As of now you have to use a LG brand disc burner. Their laser can burn into the harder surface. I picked some MDISC dvd's a few months ago and putting thru my personal testing. I have frozen them, hung them in a sunny window and had no data errors. Check out their web site at www.mdisc.com
I am using them to archive some family photos. These would be great for something as important as wedding photos/video
Back in the G3 iMac days I found that Verbatim disks gave me the fewest failures.
I've been loyal ever since, although this is probably just superstition at this point. I suspect that all burner hardware and software is a lot better than they were back in 2002.
But hey, even if there's not a real reason, being a happy customer for 12 years is still something worth mentioning.
I second the recommendation for MDisc. This seems to be a game-changing invention in the realm of long-term storage solutions, and the fact that it is backward compatible with DVD technology makes it hard to resist.
