I get exceedingly poor picture quality, freezing and pixellating only on sky sports ashes channel. Watching cricket is impossible.
Is it all the time or only at a specific time of day ? A VM engineer told me once picture quality issues can be caused by too many people watching a particular channel at the one time. TBH I do find this hard to believe if it was true football fans would be screaming from the roof tops.Call 150 and choose Tv faults to see if they can find out why only one channel is like this.
