In fact, YouPorn is blocked in many country like German, you may need proxy to view this website for it's porn videos.
This scrip can only help you download one video at time, the format will be FLV which can't transfered to your iPod.
I would like to recommend other good tools for you:
Download YouPorn Videos (How to download YouPorn videos)
.
Download YouPorn (Online website to download)
.
YouPorn Downloader (Youporn video downloader)

...
Enjoy it , make sure you are 18 years old to use these tools and go to YoPorn site.
