...i am not sure you would be able to get people to stay on your site. youtube already allows for people to comment...
and does a good job connecting related videos.
I am assuming that having the videos themselves will provide no particular boost in rankings
If your videos are engaging, people will stay on the site longer and be more inclined to view other pages thus bringing down the bounce rate, which in turn should help rankings.
