I'm not sure if this is a well known fact, as I just learned this moments ago. I don't have the direct source, so I'm just going to quote the information and provide a link to where the info was given. full post can be read here: http://www.shacknews.com/chatty?id=26824104#item_26824104 When the OP replies to where he got the information, I will update this post. UPDATE: The OP says he works for Nvidia and the statement about transcoding is his own words. He said he did not specifically work on the code (he works in developer relations department). He has a long post history and is a trusted member of that community so I believe everything he says.
