Pete - the reason it is pausing is to do with streaming speed. The data has to be buffered first then played back. What is happening here is that the playback is faster than the buffering, Press the pause button and you will see the buffering grey line move slowly left to right, when you press play again the "play line" is a darker red colour and follows over the "buffer line"

Richard - I did edit a lot of stuff out because I wanted to keep the upload to a minimum size. There was a lot of overpowering background noise (probably me!) on the intro. Sorry about the poorer quality of part 2 & 3 but, again I had to squeeze the file to a minimum as I was hogging the family computer! Part 1 was a bit better but took ages to upload.
