Here are some interesting links:

Sorry but there's no commentary in this one, Just testing out the new capture device I got from Maplins, not so shabby as it only cost £19:99.
I can tell you one thing for certain, YouTube compression has not been kind to this video clip. So it's perfect for YouTube.
Sorry if it's a bit boring =-)
