What ports do you have available on your TV to connect to? For most flat-panel screens there should be some combination of HDMI, DVI, component (3 x connectors, red / green / blue), S-Video (single round connector with multiple pins), and composite (single yellow connector). For connecting the Apple TV, you should be aiming to use HDMI or component and it should work fine.

Let us know what ports are on the TV and I can suggest what the best way to connect the iPod will be...
