Answer 1

Great! I needed a way to grab a whole playlist of videos.

In Linux, this is what I used:

y=http://www.youtube.com; f="http://gdata.youtube.com/feeds/api/playlists/PLeHqhPDNAZY_3377_DpzRSMh9MA9UbIEN?start-index=26"; for i in $(curl -s $f |grep -o "url='$y/watch?v=[^']'");do d=$(echo $i|sed "s|url\='$y/watch?v=(.)&.*'|\1|"); youtube-dl --restrict-filenames "$y/watch?v=$d"; done

You have to find the playlist ID from a common Youtube URL like: https://www.youtube.com/playlist?list=PLeHqhPDNAZY_3377_DpzRSMh9MA9UbIEN

Also, this technique uses gdata API, limiting 25 records per page.
Hence the ?start-index=26 parameter (to get page 2 in my example)

This could use some cleaning, and extra logic to iterate thru all sets of 25, too.
