I am a complete newbe. I 'd like to ask folk if it's possible to use get_iplayer with mediahint.com. If yes I would like to ask how to set configuration of the net and so on.

Hi,
Sorry, but as far as I know interfaces into anything other than iPlayer is a no go.
You can program the interface between get-iplayer and <whatever> yourself but it is not a supported thing. Your programming is your own to debug and fix in essence.
