I have a laptop Inspiron 5110N.I recently tried to burn a movie to a RW+ DVD, by using the Windows 7 integrated burner.I had previously burned something else, but removed it in order to put the movie on the DVD.However, when the movie started to get burned on the disc, an enormous time left appeared.Something like 30 minutes, just for this movie.It almost freezed at one point and the DVD writer was making only one sound - ot sounded like it was starting to do something, then it slows down and stops, and the same thing all over again.I have to mention that several months ago my laptop fell on the ground, but the DVD worked fine, at least for reading discs.Can someone suggest what the problem might be, and if possible, to tell me how I can check whether the DVD component of the laptop is still ok or it is already broken?
