I have some more thoughts on the coastering of the Verbatim DVD+R DL media when burned at 6X. Of the discs in the second 3-pack of the media, 2 were burned on the second drive (now returned), and 1 was burned on the new drive. All 3 were coasters, and all 3 were burned at 6X using DVD Decrypter. The first box of discs (burned only with my second drive) had one disc burned at 6X using Nero, one disc burned at 4X using Nero, and one disc burned at 4X using DVD Decrypter. So, the problem I experienced could have been bad media--it's highly unlikely that both drives are bad. However, upon reanalysing the problem, I think the problem was that I burned the disc with DVD Decrypter. The only successful 6X burn I had was burned with Nero! Furthermore, the coastered discs did not fail to write during the burn process--DVD Decrypter locked up after the finalization stage. I know that there are probably many people out there who have made successful 6X burns using DVD Decrypter. But, I am a programmer, and I know, that it is very possible that the burning part of the DVD Decrypter program may be buggy and the problems may only affect certain hardware configurations. This is all speculation--but if I had to venture a guess, my guess would be that had I burned any of the discs in that last 3-pack using Nero (at 6X), they would not have been coasters. However, because this still could be a media problem, I'm going to ask Verbatim USA to replace the discs under warranty, so I can test discs from another batch and not spend more money.
