In which case I certainly wouldn't rule out signal issues that could also be impacting on your broadband service - but others in the broadband section are far more familiar with that.
Just on the TV, if you've already rebooted then your next step is to report the fault. This is primarily a user-forum with VM staff picking threads up (anything upto) a few days later, so you need to call TV Faults to progress this. If you have a VM phone, call 150, otherwise 0345 4541111. Follow the options for "I have a fault with my TV service".
You've not mentioned whether you have a TiVo or a V6, but if you have a TiVo then you may also want to consider a swap/upgrade to a V6 box which is a much newer and quicker box. You have VM broadband so meet the criteria.
