latest version (2.3) has an entirely new audio track, instead of just from the camera's microphone. We have painstakenly replaced the camera's audio with audio from the console and synchronized it as closely as possible.

What's a CDN? It's a Content Delivery Network (click here for a video explanation). We are using a service (Vitalstream through YourHost) that stores the streaming file in servers all over the world. When you click on a CDN video, we automatically determine which server is closest to you and how fast the connection is, then it begins streaming from that server to you. You can also skip to whatever part of the video you are interested and it will instantly go there. The other links are regular, single servers with space graciously donated by PlymouthBrethren.org.
