Many of my channels are distorted by pixelation. I've phoned, waited 25 minutes to speak to somebody who sounded like she was fed up reading answers off a page. Try this, try that, leave it for ten minutes, I'll send a signal to fix it. If it doesn't work call back, hang on another 25 minutes. This signal I'm sending will definitely sort it.... Still got the problem.... Has anybody managed to get this sorted? I'm ready to pull the plug after over 20 years.
