I would concur with the recommendation for printable TYG03 (Taiyo Yuden, 16x DVD-R), though I cannot speak from experience.
You will not find any silver-ish bottomed DVD±Rs.
If you’re prepared to sacrifice point 1 as well (and can settle for an 8x DVD+R) I would suggest Taiyo Yuden 8x DVD+R, it’s mid is YUDEN000 T02.
Of al the disc types I’ve used, YUDEN000 T02 has been the only one (save for a single CMC MAG E01 ) that has been reliable, given no coasters, and never shown signs of accelerated deterioration.
(OffTopic)I too once bought some old and unpublished TV shows from a replicator/dealer in Canada, burned on TYG02, and it too has gone bust (they were called TheMediaDepot IIRC) most likely because they hadn’t a clue what they were doing (using thick, gooey paper labels on DVDs for example :a ) (/OffTopic)
