Youtube is a hellhole.

To make a video URL start at a particular time you can define it in minutes and seconds by adding &t=XmYs to the end, where X is the minute and Y is the number of seconds, for example http://www.youtube.com/watch?v=rRTSSzccALA&t=1m0s

• Youtube-dl - Great tool for fragging YT vids is various formats, or just grabbing the audio.
