How to connect my Freeview TV to my Freeview Video/DVD player?

Hi
How do I connect the above without compromising the picture quality on the Tv. At the moment the Freeview on the Video/DVD player takes over the Freeview on the TV when I try to record. I have tried just having the aeriel connected to the TV and the Scart connecting the TV to the recorder but then when you try to record - it says "no signal" any ideas.
I have got a plasma TV with 2 HDMI sockets
