Did anyone notice?
I had Virgin for a year and while the TV service, when it was working, was actually quite good, I was plagued by problems:
1. The TV service on a certain set of channels was digitally corrupted (pixellated) and two fruitless interventions (many days) later by an engineer who came to the house, I eventually got through to him that he'd temporarily fixed it (he didn't believe me at first). So he then went back to the street junction box and got it working. Apparently he fixed it by swapping my port over (which was defective) with one of my neighbour's. I assume my neighbour wasn't too pleased with that temporary workaround
2. Their DNS service regularly (almost on a daily basis) went down, stopping all connectivity not related to the TV service anywhere from 30 minutes to 4 hours
I've switched to NowTV and don't get any of these issues now and the service is £15 cheaper/month
