An attempt is the DVD definitely value

Once I even had the cleaning DVD can go through, he reads again without problems all types of DVDs. I could him however even after multiple passes not to move back DVDs to describe. Since I had this error for some time and the device has always been very picky when choosing the blank, I'm assuming that this is not a pollution but a defect in the unit.

The DVD works as described, is easy to use and definitely for the price for devices that no longer work as usual, worth a try. However, it should be clear that it must be not always necessarily to deal with pollution, if a drive is not working properly. Technical defects can be incorporated naturally not resolve, therefore, despite partial success, to me the full number of stars.
