I thought I'll try times from the cheapest burner, there is, after I had read in a forum that almost only one type of burner cast installed by the industry. But that can not quite agree. My new burner does what it should, it does not here. Rewritable discs should it not possible to offer, for the too expensive. You can save money by buying the same write-once. The fact it burns even without problems, but sometimes they just do not want it read, especially for DVDs. After I felt hundreds of CD-RWs, DVD-RWs had wrecked and was allowed to look at the green bar of Windowsexplore for half an hour while reading a burned DVD, and this continues to move at a snail's pace, the decision was made, after only three months had a other burner ago. With the LG I am now satisfied.
