Add to that Verbatim made in Singapore NOT India. I have read, and now have the unfortunate personal experience, that Verbatim DL made in India can be very problematic. I just received an order of 100 DVD+R DL Verbatim made in India, and of the first 30 discs I've burned, 11 are coasters. For perspective, I've burnt in excess of 400 Verbatim DVD+/-R DL made in Singapore with only one coaster that I can recall.
Perhaps Lite-On and Plextor need to come out with a firmware revision to properly work with this media, or perhaps it just sucks ass....
