Tuner advice please

[launton]

Hi

Can someone please point me in the right direction with my VU+ Duo 2? It came originally with a dual satellite tuner and I've ran it like that for a long time, I got a new single tuner and added this to the box. In tuner settings it's seen as Tuner C (others are A & B) and I have set it to Astra satellites the same as the other 2. On the rear of the box I have connetced 1LNB cable to tuner A one LNB to tuner C and looped back to tuner B from A because I only had 2 feeds. On a test I could not record 3 programmes at the same time so I looked in settings and I have some other options in the setip called loop through and equal to and I have no idea what to set them to. I did not move the original tuner, I added the secondary one to interface 2 in the box inside. Can anyone help me set it up properly please as I dont think all 3 tuners are working.

Thank you

John
