I'm very sorry to learn about the problem you're experiencing with your On Demand service at the moment, are you getting this error message when trying to watch anything in particular or when trying to watch everything?
I've located your account to run some tests on the set top box and we're not detecting any errors from our end at the moment.
We're looking forward to hearing from you and getting this resolved.
Been with Virgin since August....ridiculously slow Tivo, paying for 200mbps but rarely getting more than 35, and now on demand unavailable for four consecutive days (that we're aware of!) Christmas looking grim, but Sky Q beckons!! (PS phone works fine! But no one at Virgin's end to answer it! 😭 )
I'm sorry to hear about the problems with your On Demand service, are you still experiencing these issues? If so, is it with all On Demand content or certain programs / channels? Also, are you noticing any difference with HD and SD content?
Sorry for all the questions, we want to get to the bottom of this issue as soon as possible.
