My pleasure. I came back with few shorter youtube-downloaders.

For Perl>=5.14.1
use LWP;use URI::Escape;$u=\&uri_unescape;for(@ARGV){($y,$_)=m[(.+m)/.+[=/]([\w-]{11})] or next;&$u(($l=new LWP::UserAgent)->
get("$y/get_video_info?&video_id=$_")->content)=~/ap=url=([^&]+).+&title=([^&]+)/;$l->mirror(&$u($1),&$u("$2.mp4"=~y#+/# #r))}

For all versions of Perl
use LWP;use URI::Escape;$u=\&uri_unescape;for(@ARGV){($y,$_)=m[(.+m)/.+[=/]([\w-]{11})] or next;&$u(($l=new LWP::UserAgent)->get(
"$y/get_video_info?&video_id=$_")->content)=~/ap=url=([^&]+).+&title=([^&]+)/;$l->mirror(&$u($1),do{$t=&$u($2);$t=~y#+/# #;"$t.mp4"})}

One-liner version:
perl -MLWP -MURI::Escape -e '$u=\&uri_unescape;for(@ARGV){($y,$_)=m[(.+m)/.+[=/]([\w-]{11})] or next;&$u(($l=new LWP::UserAgent)->get("$y/get_video_info?&video_id=$_")->content)=~/ap=url=([^&]+).+&title=([^&]+)/;$l->mirror(&$u($1),do{$t=&$u($2);$t=~y#+/# #;"$t.mp4"})}'
