At the moment no but we are working on a second version of the video player that will allow you to see what you've watched and set bookmarks up. The system is still not even a month old yet so we're planing to add new features. If you think of anything else you'd like to see please do let us know.
Expect it at the end of the month.
From a readers' Q and A column in TV GUIDE: "If we get involved in a nuclear war, would the electromagnetic pulses from exploding bombs damage my videotapes?"
