I have a new Toshiba laptop, Windows 8.1, using an Asus external USB 2.0 portable Blu-ray burner. I just received a pack of Verbatim SL and a pack of DL discs. I have burned a couple of single layer Blu-rays and they worked fine. I started on the big project of burning the Star Wars The Complete Saga Blu-ray set. I burned the first disc in DL and put in in the player. The menu came up, I selected Play, the 20th Century logo came up, and then the player spit the disc out! I used the menu to select another portion of the movie, but still no playing. I tried a second player, and the movie wouldn't play on it either. It will however, play on the computer using VLC. As these discs are not exactly cheap, I'm trying to keep the testing to a minimum, so I'm asking for opinions. Has anyone already copied this Star Wars set so that I know it isn't something weird about the discs? Or is my burner failing? Or something that I haven't thought about? Thoughts, suggestions?
