Query: Don't bother with these

I picked up a 10 pk about a week ago ...b when they are onsale ... Burned 3 coasters so far and I will try to return them if I can. BTW, I used both Nero and Pinnacle InstantCopy and tried both movies and data files. Same process worked flawlessly for Memorex DVD-R and RW, and Pioneer's bundled DVD-RW so it's not a software issue. My drive is the Pioneer DVR-105 4x DVDR-RW. Don't waste your money here.
