I'm sorry to hear that your getting pixelated picture on your recorded programmes. I'll be happy to help you.
I have taken a look at your box remotely and checked the hard drive status. And there does look to be a few errors there that will be causing the issue. In order to get this fixed, I will arrange for an engineer to call round and fix this for you.
I will send all the details in a private message. Look for the envelope icon above.
