can anyone advise or point me to a site that explains how to record from itv player then edit a section down into a clip, as i might be on telly soon and want to put it on the website.

ITVPlayer, Iplayer, all the terrestrial channels have the ability to have the files pulled down using different utilities that don't have the DRM embedded and thus are easier to work with.  (That doesn't mean that you are free to breach the copyright, indeed even editing a clip of your own appearance on TV you should ask the copyright holders permission to post the clip on your website)

For instance for the BBC Iplayer there is get_iplayer and get_iplayer PVR that allow you to download anything available from the BBC and save it out as an .mp4.  The program works by having the BBC website believe you are using an iphone/touch/pod to browse the site, we have used it to place video on our Ipod Nano ready for longhaul flights etc.
Get_Iplayer used to also support ITV programmes however that support has now been dropped. however, as stated there are utilities available for all the channels.  Just do a simple Google search for the one you might need.
