I'm trying to gather information on what brands of dual layer DVDs are the best to use (archival longevity being a key concern). I use TY CDRs and DVDRs, but they don't seem to make dual layer DVDs (at least I haven't seen any for sale anywhere). Any recommendations about good dual layer DVD brands would be much very appreciated (or, any cautions about problematic brands would be helpful too).
Thanks in advance for any advice.
