I would not recommend these disc as I have had 5 coasters and thats enough for me. During playback the picture freezes and glitches. I have tried burning at speeds from 1-16 and I still get errors. I normally use TDK, Memorex or Verbatim without any problems. I have now put 95 coasters in the bin and purchased 2x 50pk Memorex discs from Maplins for twenty pounds and these work fine. Finally spend a few more pounds and get quality discs and save your self the disappointment.
