Why is there always pixelation when the rugby is on? I can’t even swap to Freeview as game is not on Channel 4. £18/month for a sub standard picture is unacceptable.
Can't say as I've had problems, so there isn't "always" pixellation when the rugby is on BT. This would suggest you may have a localised fault, either in your area or with your box.
Check the service status page https://my.virginmedia.com/faults/service-status for known issues, if there's nothing shown then the chances are Virgin don't know you've got a problem. Call them, report it and give them a chance to rectify it. You're right about it being unacceptable, once VM have been given a chance to resolve.
