I've been having nothing but trouble with the Memorex 16x DVD-Rs I got. 2 out of 5 burns fail. I had Memorex DVD+Rs before these and I went through 25 with 1 failure. Sadly I bought a 50 pack of these and didn't notice they were DVD-Rs vs DVD+Rs. Everything else BestBuy had was off brand junk as far as I could see. Been burned when buying off brand CD-Rs.
