TV, freeview, DVD and video set up.

Question

Hi...I've recently got a new Freeview as my old one went wrong. We done the set up as it said in the book but now the Freeview will only tune in on AV. I don't have the option to tune in the video player. My son connected the new Freeview up and said he'd moved a lead from the DVD now I can't record Freeview. I have spent about 15 hours retuning the TV but to no avail. Is it a wiring/scart problem or is it that Freeview is only able to tune in on AV. Before, using my old Freeview, I had that tuned in on Channel 6 and the video on Channel 9 and could record. Any help would be grately received as it's driving me mad!
