Hi,
You might want to try out
Social Media. They have a pretty good looking script. However, their forum is closed, so I never got a chance to look over what kind of bugs are being reported by users. My experiences with these scripts are that they are very difficult to stabilize, so without any way of looking at current user experiences, I stayed away from this script.
Here is another one to look at:
TopMediaScript. Their forum is open, so you can check it out for comments.
One word of warning. YouTube has recently changed its TOA, and if you are running a website with YouTube videos, expressly for ad content, they will come down on you.
Hope this helps,
Rich
