I'm not sure how well that would work, but the first thing that comes to mind is that if you don't create the buffer until the user presses the pause button then you absolutely can't pause on the same frame they were watching when the button was pressed (since it's already been displayed to the monitor and not written to disk). At best you could pause at the next frame, which is probably acceptable to most people, but this would really depend on the overhead required to open the new buffer file and start writing video to that file. > idea 2 > Is it possible to send video to the screen and also write it a file > (albeit with some delay in writing it to the file)?

However, the real problem, as you mentioned, would be the transition from live video to the buffer. I'm not sure it would even be possible to determine which frame in the buffer corresponds to the frame that is currently displayed on the monitor. To be honest, I don't think this feature is very high on the list for most, if not all, of the developers since, to my knowledge, the vast majority of myth users rarely, if ever, use the live tv functions. I can't remember the last time I watched live tv since I've always got a disk full of recorded shows that I can watch commercial-free. Brad
