Hi guys

I have searched around the forum but cant find a guide or info on how to set up my vu+ usb tuner turbo for a cable line.
If im missing it can somebody direct me? If there isnt one can someone tell me where to start?
I have a virgin subscription my box is a vu+ duo with two sat tuners which i have been using for years I have plugged the usb cable tuner in and it isnt showing on the tunerconfig. (only tuner A/B sat) I read something about enabling the new tuner first please help guys!

thanks

(its an old openvix image im still using as have problems with software update)
