I copied a Star Trek Original Series HDDVD to my hard drive last night by exploring the disc and copying to a folder. The file was unplayable until I turned it into an iso and mounted the image. The disc now begins with the lead-in and goes to the title menu but only the first episode is listed. When I attempted to push the button (with my mouse) to change to another episode, it just starts the first episode. Is there an issue with copy eposidic content to the harddrive and playing from there? Is this an issue with the player? What are the SLY files that are created and was any harm done when I just deleted those files? I've tried a search on this both here and abroad and found no answers. I did see that the SLY files are Slysoft's doing but wanted to see if I screwed something up by removing them. Thanks for your help.
