When I put the DVD in, a window pops up asking me what I want to do, but I only have three choices: play the movie using Windows Media Player, scan it for security threats, or close the window. I can't seem to rip it; it's almost like it's copyrighted. I use Windows 7. Is there any program on there that I can use to put a file of it on my computer, or is there a program I can download to do so without damaging the DVD's data? Thanks!
