Welcome to the Community Forum and thanks for your post. I'm sorry to that you are having a problem with your TiVo® recordings.
I've been able to run remote testing to your equipment and can see a problem with the TiVo® tuner, which will cause a problem with recordings. I'd like to arrange an engineer visit so that we can get this fixed for you.
I'll send you a private message requesting further details. Just check the envelope icon at the top right of this page.
