Ok , I have a ASUS DRW-0804P Burner (i think). I have been burning dvds of a little while and now have come across several problems. I bought a gift box thingy of fishing videos (Fishing WA Series) and i want to back them up. Only when i put them in i get a message saying DVD Shrink encounted a error and cannot continue. Invaild DVD Navigation Stucture. By the way i can copy other videos i have brought from the Video store ok. Its just this set. Well that is the first major one. The other is : When i copy a normal DVD it goes through the open disc and then i click back up after it has finished doing its thing. The problem is that when it coms turn to insect the blank cd it tells me that the drive does not support this disc type. In the box where it comes up "checking disc" it asks me for a DVD+R/RW, DVD-R/RW. See the thing is that i am inserting a DVD-R and that is the one it rejects. The DVD+R is ok and burns fine. Is there any way i can get it to burn on to these disc? ( Just bought 100's of them and dont want them to go the waste ) Cheers guys !!!
