I'm a new customer to virgin. Since I've got my box the sound lags behind when watch apps, netflix, amazon video, etc.
When you start watching a programme it is fine but after a couple of minutes the picture and sound are out of sync by as much as a couple of seconds. If you leave the programme and go back to it they have synced up again but the sound will lag behind again after a few minutes viewing.
I have tried resetting boxes, had a look in settings but don't see anything, any help would be appreciated. Thanks
