ja pouzivam vyhradne DVD+R (nemam ako hlasovat :-O ), pretože, citujem:

There are a number of significant technical differences between the "minus" (actually strictly incorrect - it was a hyphen prior to the introduction of the DVD+RW format) and the "plus" format, though most consumers would not notice the difference. One example is the ADIP (ADdress In Pregroove) system of tracking and speed control being less susceptible to interference and error than the LPP (Land Pre Pit) system used by DVD-R, which makes the ADIP system more accurate at higher speeds. In addition, DVD+R(W) has a more robust error management system than DVD-R(W), allowing for more accurate burning to media independent of the quality of the media. Additional session linking methods are more accurate with DVD+R(W) versus DVD-R(W), resulting in fewer damaged or unusable discs due to buffer under-run and multi-session disks with fewer PI/PO errors.
