I am an newbie. I am trying to burn to dvd using benq dvd ew1621 external drive with windvd creator software. I made a movie in windows movie maker and imported it to windvd and then tried burning it. It seems to go through the whole procedure but isn’t burning to my dvd. I think its because of the speed that is set at optimal. I select benq dvd where asked then speed only gives me the choice of optimal. I would like to change the speed to much lower but don’t know how. If anyone has any ideas I would appreciate. the movie is supposed to be a christmas gift for family. I think that is the issue but as I am unfamiliar with burning dvd, hope I haven’t messed up else where.
