I spent 20 minutes on the line to a call centre today and was unable to get an answer to this. My Sister (not a Virgin customer) was able to watch all 4 on ITV Hub. It must be a Virgin thing ? No clear answer from the lady in the call centre who had as much trouble making me out as I did her (I am from NI). Spent her time trying to sell me a V6. What is going on, anybody, please ?
