Hi, got a few problems, first off, on playback the picture keeps pixilating in horizontal lines, second when watching normally every so often the picture freezes for a second or two and then catches up, the sound is OK. And third, sometimes when I exit the portal the machine just freezes and will not respond to anything except turning it off at the mains and turning it back on again. Thanks for any help.

What is the signal strength and quality as reported by the Humax on the channels where you get this problem?
Signal strength and quality 100%.

Signal strength and quality 100%.
If your signal strength really is 100% then it is quite likely that is the problem. Too high a signal strength can overload the tuners. If you have an amplifier in the aerial cabling then try removing it (or turning down the amplification if it is variable gain) or try a variable attenuator in the aerial cabling. I would suggest aiming at a signal strength of 80%. Signal quality of 100% is fine.
Hi again, there is no amplifier but I can see the TV mast from the window so that might explain why. Would this also be the reason for the picture breakup in playback?

Yes. What transmitter is it?

Ok that is a main transmitter so I definitely think an attenuator in the aerial feed will help.
