I have a nec 1100A dvd+rw drive and I am using dvd shrink and burn at once to backup my dvds. Everything looks like it works great and the movies play on my computer but do not play on any dvd player that I try. When I look at burnatonce info box it seems to think that the media is a cd-rom and it says that it sees the dvd+R media but it is not supported. Is there a setting I am missing? Any help would be great.
