Query: Used To Be A Quality Product, But ...

I've used Verbatim blank DVD's for the past few years because they were always so reliable, never a "coaster" in the bunch. [That's in contrast to Sony and Memorex, where each attempted burn was always chancy.] However, my last stack of Verbatim's started out OK, with no problens, then 2/3 of the way down the stack I started to get write errors when burning. I dropped the recording speed from 16x to 12x and that helped some but even then a few were unusable. Thinking my DVD recorder was getting dirty, I invested in a cleaning disk but that offered only a marginal improvement. I am now reluctant to spend money on a product that has gone from ultra-reliable to iffy. If anyone has located a media manufacturer whose DVD reliablity is superior, please add a note to this set of reviews and let us know who it is. Thanks.
