I'm using windows vista x64 home premium. I burn a lot of videos from my Dell studio laptop on to DVD RWs using windows DVD maker and I have been having problems lately. When I go to erase my DVDs (usually about 3-6 at a time) the first will go without a problem (autoplay starts the disc in windows media player, I close that then click "erase this disc" in my computer and it clears) but then sometimes when I put in the second one the autoplay doesn't activate, "erase this disc" doesn't work (unless I restart. then the whole process starts over again), but I can still view and play the media on the disc which leads me to believe that it is a software problem. Any help at all is greatly appreciated.
