I was wondering what blank dvd's would be the best to burn with? I have a sony 720a burner and it seems to be picky with the dvd's it will burn. sometimes it burns dvd's useing nero and say 100% burned and when i go and try to watch it on my dvd player the player says no disc. so i have to waste another hr. re-burning the dvd. Any help??? Or is something wrong with the dvd burner?
