Now in beta, the Google Video Search looks very promising. It searches through the closed captioning text of programs from a limited subset of channels (during the beta) to find matches. The results are returned with screenshots. The neat thing is that it also lets you know when the show is on next. The weak link, of course, is that you can't really view the content online. Now that would be very cool, but in the current DRM environment it's probably not going to happen unless things change dramatically.
