thanks for the response, but it wouldn't be that much fun just to buy any dvd burner right? Of course, good, clean scans aren't the be all and end all, but at what point do you stop the comparisons? Is there any way to determine that an excellent scan might in some way contribute to a disc that lasts longer? or does it come down to dye or other more basic factors?
There's been a number of independant longevity tests on DVD media now... probably the one easiest to find would be the one done by C't, summerized here:

It seems that longevity has a lot to do with the way the disc itself is manufactured, and somewhat to do with the dye, and burn quality compatability with the burner/media. Some discs that KEEP popping up near the bottom are Ritek and Prodisc... other discs like Verbatim and A Grade Optodisc (Samsung or Acro Circle brand are good choices) are almost always closer to the top. Discs frmo Taiyo Yuden can go either way, but generally Plextor brand seems to perform better, and Unbranded TY seems to perform worse. I think Sony brand TY is also more likely to perform better in the long run.
