I run CarraraLounge for about one year now and it have a lot of video tutorials created by me and other users... but now Youtube accept HD videos and this make the life more easy: you can upload in just one place and show everywhere.
The problem with SMF was that its a forum script (I also had a lot of plugins for it), but very hard to run alone. In thsi new software, everyone can handle your own content very easy and interact more with other users... i Hope!
