Query: 100% failure rate

I have a Pioneer A06 (DVR-106D), I normally dont have any problem burning DVD-R's. The spindle of Memorex DVD-R Printable discs simply do not work (at least with the Pioneer A06). I went through 25 of the DVD's and had the same watermarking problem mentioned in other reviews here. I had a 100% failure rate on these DVD's. The video would freeze way through the movies and the menus didn't work. I am working on getting Memorex to replace them with the non printable surface DVD's. Stay away from these if you have Pioneer DVD burner. Try the TDK 2x DVD-R's... they backup video beautifully!
