I'm sorry you are having an issue with Intelli-Studio. With the information you have provided, contacting Samsung Service (please visit Samsung's website in your region for support numbers and links) would be your best next course of action.
I'm working on Windows Vista on the latest version of Intelli-Studio for my camcorder. An hour ago, the program was working fine and dandy, but after leaving it open for half an hour whilst working on something else, it crashed as soon as I clicked on it.
I closed the program and started it again but the mp4 files appeared without a thumbnail, just a grey generic 'intelli-studio' waterprint. When trying to open the files. the video window was functioning, except where the video was SUPPOSED to be, it was just black and the video was apparently 00:00 minutes - even though on the Intelli-Studio desktop it recognises the time of the video. When I try and do anything other than save the files, the studio crashes and I am back to square one.
I have tried restarting the computer, logging in and out, leaving it for ten minutes to load but NOTHING is working. I have tried for two hours now and I am getting fed up. The video files are fine and the camcorder itself is fairly new, I don't understand what the problem is!
