We're having ongoing issues with the audio and video getting out of sync on our new Vodafone TV box. Starts ok, then as we're watching they eventually drop out of sync. It's unbearable. We're still using our MySky box it's that bad, and will likely tell them to take away the VodafoneTV instead!
This also happens to me and is very frustrating, i suspect it has something to do with the ridiculous need for WiFi / ethernet extenders - as opposed to being fully WiFi capable. I would love to hear from Vodafone as to what might be causing this and what can be done to recitfy it.
