Q: I've set up the PVR as per instructions, however once I have started to record, I can not change from the channel. I thought this was a twin tuner?
A: Easily solved. In the box that came with the PVR you will have noticed a very short "Patch" RF cable about 20cm long. Connect this cable to the "Loop Out 1" connector to the "ANT IN 2" connector on the back of your PVR. Problem solved.
