I'm sorry again for the problems you're experiencing with the Youtube app at the moment, it would be great if you're able to check any other TiVo boxes you've got at home but I'd also like to take a closer look at this from our end for you.
Unfortunately I've not been able to accurately locate your account using your forum information so if you'd like me to do that, could you respond to the private message I've sent with the requested information? You can view the message by clicking the envelope on the top right of this page.
Thanks for sending me the information, I've been able to run some tests on the set top box from our end and we're not detecting any major errors at the moment but some of the signal isn't as strong as we'd like it to be.
Are you experiencing issues with your On Demand or Catch Up service at all? Or any other applications?
