I had a freelance make me one earlier this year but for some reason it would not play in several browsers, which is very annoying to our viewers. I need one very simular to the ones found on these pages; [login to view URL] [login to view URL] The set up that these sites have is exactly what I need. The player will be use on each blog post.
