Everybody raves about Verbatims, but I have to agree with someone that said that they changed their formulation. If you have a recent-make DVD burner, they are fine, but if your DVD burner is a few years old, it won't properly burn the "new" Verbatims.
My laptop is from 2005, it has a dual-layer/dual-format DVD burner, and it can't burn the "new" verbs. Sometimes it won't even see the blank disc. Yet it's fine with some TDKs.
