Use caution if you order this product. I have this one, along with all the other DVD comic collections (Fantastic Four, X-Men, Hulk, and Avengers), and while it's much nicer to have all this stuff on one DVD rather than 16 CD-ROMs, I have had many problems with this one. Specifically, of the 40-some different DVD drives I've tried this disc on the PC, not one of them could see any files on the DVD other than a folder with "1960"s stuff in it. At first I thought I had a defective disc, but after I tried it in a MAC DVD drive, the entire disc came up without a problem! I suspect it has something to do with the dual layering and PC drives not being able to read one of the layers. It seems they didn't do a very good job at product testing to make the DVD able to be read by different kinds of DVD drives. So unless you have access to a MAC that can burn PC/Windows DVDs, you may be out of luck on being able to read all the files on this disc.
