Is there a way to embed Facebook videos within Snitz forum?
I've thinking along the lines of using their developers tools (https://developers.facebook.com/docs/plugins/embedded-video-player), possibly where the code can be added into the forum code and the link to the video is posted to a form field, entered into a database table or column and then retrieved in a post

Is this doable or too complex?

I would think it is doable, I think there are some video mods on snitzbitz, looking at those may be a good place to start

Yes there is a mod on snitzbitz for it. http://www.snitzbitz.com/mods/details.asp?Version=All&mid=317
