How to tune a Sony DVD RDR-HX780 to a Sony Bravia KDL-32EX400



Please Help!!!
We are trying to tune in our DVD player/recorder RDR-HX780 to our TV KDL-32EX400. We are following all the steps in the manual but to no avail. We can’t get a good digital picture or any freeview channels on the DVD. We have a UHF ariel.

Any advice would be most welcomed (before I throw the lot out the window)!
