Youtube Feed

Hi,

With the newest version Pressforward that is said to work with Youtube RSS feeds, I cannot get it to work. And there sems to be no documentation for YT.

I use PF for text but really want to use it for importing video also.

Can someone please tell me how to setup a Youtube channel and/or video as a Subscribed Feed?
How do I find the rss feed for a video/channel in YT?
Do I need an API key for YT?
Please provide a sample of the full syntax so I can compare what I need to produce for PF.

Thank you,

Will
