Only our main 42" 1080p TV has an HD tuner but it's generally used with VM's V6. The TV/DVD 720p combo in the kitchen only has an SD tuner but it can work with the laptop via an HDMI lead and use VM's TVgo site, so we could cope if the SD transmissions were scrapped.
I've never used the VM TVGo website, just the app, how's the picture quality?
