As you may have realised by now it's far quicker to phone for help as this is primarily a user forum. Whilst the mods are about it can sometimes take a few days for them to reply. I think you have a signal issue which is odd if you've only just had TiVo installed as the engineer should have checked your signals very carefully. TiVo is very sensitive to having the correct signal level.
I'm sorry to hear that you're getting picture disruptions on your TiVo® service, this isn't good to hear.
I know you've mentioned you have requested to cancel, if you'd like to give us an other go we can help get this fixed for you. I have carried out some checks here and there is a problem with the downstream power level which can be fixed by one of our engineers.
If you're willing to give us another chance, I will be happy to arrange for an engineer appointment for you. We're here to help if you need us so let me know what you decide
I look forward to hearing from you.
