Hi, Im in the Uk running VU and Tvpack. I have a Nova-T 500 DVB-T Tuner and HVR-4000 installed

When I run tv set up with the aerial plugged into the HVR-4000 only it detects a signal, and when i connect the Nova-T 500 only it also detects a signal.

If i have them both connected it only sees a signal on the HVR-4000!

I also cant run a manual set up because the first question it asks is if you have a satellite or aerial set up and you cant choose both!

Does anyone have any ideas what i am doing wrong?

Thanks
