I'm sorry to hear that your frequently experience this error when ordering On Demand content. I'll be happy to help check this out for you.
I have carried out various checks with the box remotely, there are a couple of things I have picked up. Firstly, this error usually relates to high demand that occurs on the network (More common at peak times) and I have raised this to our fault teams for monitoring to help improve the situation.
Secondly, I have picked up a signal issue that maybe causing other potential symptoms. Can you please let me know if you have any issues with your recordings or picture on recordings, live channels?
Let me know and I can help further

Thank you for coming back to us on this, I can see some issues with the hard drive on the TiVo® which may cause sporadic issues, some of which you've mentioned, so ideally I'd like to get someone out to take a look at this.
And whilst I'm no broadband expert, I did run some testing on your broadband too, and can see some issues with the power levels feeding your SuperHub. I asked one of my colleagues to check things out, and they advised me that a technician would also be needed for the broadband too.
I'll send you a private message in order to get things arranged. Please look to the top right of this page where you'll see a purple envelope icon, click on this and you'll see my message.
