The ECC approach is nice. My current solution is to burn two copies of each archive DVD. If the media deteriorates and there are unreadable sectors, I use the second copy of the DVD to replace the dead sectors.
This is done using software which has a Bad Sector Mapping function, and a Patch File function. I have used Media Doctor to do this job. I wrote it up here: http://www.cyberdelix.net/tech/recover_cd_dvd.htm This said, I want to dump DVD as an archive format (I find that only certain drives will read certain DVDs, total PITA), I'm considering using HDDs, possibly 2.5" in a RAID configuration, in a NAS which is only fired up when needed. I suspect nowadays, 2.5" drives are more space-efficient, although I haven't done the sums.
