When I was an undergrad I used to watch videos of lectures on tape. The library had these cool videos that let you watch at double speed. The voice would be high pitched, but I was able to get through them a lot faster. These days are long gone because everything is digitized. Is there any way to watch videos at double speed, including the audio, on my Windows machine?
VLC can do this. Look for the "Faster" option under the Playback menu. And unlike those old lecture tapes, VLC will adjust the pitch for you, too.
