A few digital video editing links, suggested by 'PC How To Digital Video The Essential Guide' magazine (or PCHTDVTEG, pronounced Puc-Ted-Ve-Teg, as it is affectionately known).

www.marcpeters.co.uk - Digital director site
www.desktop-video-guide.com
www.simplydv.co.uk
www.videosuccess.com - ignoring the home study course, natch
www.fastforwardclub.com - sounds a bit hobbyist, but is actually aimed at professional 'videographers'
www.digitaleditor.com
