TD5 defender oil/filter service

I bought my amazing Defender 110 TD5 3 weeks ago and have literally loved every journey and bump!! Am intending to give him an oil and filter service and wondered if anyone had more than the 'Haynes' manual that could help - - I'm not a mechanic but I am practical, and I am told that with the right tools a service on a TD5 isn't too challenging!! anyone know of a DVD/website that may be of use? :-D

I used the Haynes manual and then sought the correct information on here when the Haynes' picture didn't look right.
