Recently signed up to VM and TiVo box frequently, briefly losing sound & picture (pixilated screen or black screen) on free view channels, apps (eg BBC I player) and on home screen. No resolution despite 3 calls to service centre.
Does anyone have suggestions as to what next?
does it happen at 10 to 15 minutes past the hour or all the time?
Only if it happens predictably at 10 or 15 minutes past (or recordings made at that time) please read here>
