Firstly it's better to start your own thread, than add on to someone else's, especially when your issues have nothing to do with theirs - I appreciate your frustration, but I've moved your post for you..
You say you've had TV problems for 3 months, but it's your first time posting here so we will start from scratch to best help.
Your picture shows pixellation on live TV channels which is often a signal fault. If you've rebooted your box once, then there's likely a fault somewhere which VM will need to rectify. Check on 0800 5610061 whether there's any existing area problems, but if nothing's reported then VM will need to pick that up. You can either call in to report that, or wait on here where VM staff should respond after a few days.
The issues with streaming are completely different - your V6 gets its internet connection via your homehub, and this connection can be Ethernet cabled or wireless. How is yours connected? If it's wireless, then please follow (on your V6) Home > Help & Settings > Settings > Network, and look in the top-right for the signal strength. What is it?
