TV search engine tells you when that show is on next

LocateTV looks like a pretty good US/UK TV listings search engine -- Lottie sez, "LocateTV is a film and TV search engine that tells you when
any show is next on air, on TV, online and on DVD, specific to your
region and channels (US and UK). It's slick and simple, with lovely
widgets, which you can embed on your blog or post to share the
scheduling info with your readers - which remains always dynamically
updated and relevant to them."
