I'm sorry to hear that you're getting this error when using Catch Up, I'd like to help check this out for you.
I have connected to your box remotely and all is looking fine from here signal wise. There's no network issues present which I'm pleased to report.
How are things looking today? If you're still getting this issue, let me know and I can help further. Also if you can ensure all leads in the back of the box are plugged in tightly and if you haven't already, power off/on the TiVo® and this may help refresh things for you.
Keep me posted, I'm here to help if you need me.
