Fans of CS Lewis' writing, such as the Narnia books, might be interested to hear footage of the man himself talking on BBC radio back in the 40's.

ListenToAMovie streams the entire audio track of a movie (and some tv shows) online. It is not a files sharing or file swapping site. And although the audio is mono and the encoding quality is intentionally set very low 24Kbs (less than AM radio quality) you can still get the gist of what's going on. They've got a fairly wide selection too.

I find that quite often the best and most useful information is not written down, but passed on by word of mouth. With the advent of podcasts it would of course be good to be able to search through those too. Well, Podzinger does just that. With some voice recognition technology, you can search in their database of audio (and video) and the results show how far into the media the word you're looking for turns up!
Google's missing a trick here. Though having bought up several companies recently (namely Adscape and Trendalyzer) maybe they'll target them for purchase too?
