Is this meant to be the case? It seemed like there should be an audio track?

Thanks a lot to the feedback, but they are just NO audio videos. in the future with more time to spend in them, i will edit them .

they look good... the two random ones I watched were okay (e.g. somewhere in the middle).

Oh, my Doh then :)

Think I was expecting a screencast with a voiceover explaining what to do as it was happening.
