I've solved the problem of the video being compressed!
It was caused by editing the video with Microsoft Movie Maker (Aren't MS products wonderful? [cough splutter])
Anyhow, to redo the other videos would be too much hard work.
They are all posted on my website now with their own page "Tillering Videos" including pt5.
I'm not going to duplicate them here. The website address is shown under 'About me' at the left. Or just google 'Delsbows'.
When it's completed I'll post some stills on this blog.
