On metacpan when you put "youtube" in the search field the first auto-complete is youtube-playlists a script that is part of the WWW::YouTube::Download module. It was last updated May 5, 2013, has zero bug reports, two five star reviews and zero failed test reports. The synopsis shows example usage that looks exactly like what I want. I install WWW::YouTube::Download with no problems and run 'youtube-playlists FLNj0f88cIMwioXOKJE89Lpw' and it returns 25 results only on a play list with more than one hundred entries. Looking at the POD there are no cli options to change the result count and looking at the code I see it is only pulling down the first page of results as xml with no mechanism for handling pagination. I consider hacking away at this program but there must be a youtube module that handles most of the work instead of just pulling in raw xml feeds and doing it all yourself. I am also surprised this program did not show up in the general search engines, only in the CPAN ones.
