Would recommend sony vegas for video, deals well with mp4. Its not cheap but a friendly pirate may be able to hook you up, hes always hanging around the bay, if you know what I mean.
I noticed since the switch over to the YouTube format that we have lost a lot of the behind the scenes material that I think a lot of us enjoyed before. It was good to get to know the players better and I think it made the fans feel a bit closer to the players.
Don't be offended, but I've never been a fan of changing lyrics. Always seems naff to me. Don't get me wrong, I like the idea of using the song, but just leave it as is.
