Welcome into the Community and thank you for your post.
The 319 error is something that shouldn't affect you too much and would require the show to be selected later that day. I have been able to run some tests on the TV services and all services you have, it looks like there is a fault with one of the TiVos, that would need to be addressed ASAP.
This will need an engineer and I would like to arrange this for you, if you can have a little look inside your Inbox, you'll see I've sent you a Private Message. You can find this at the top right of the page, purple envelope.
Speak to you soon and welcome into the Community. Ben
