Sorry to hear that you are having problem with your BBC iPlayer app on the TiVo. Is this working for you now?
If you are still having problems with the app, try rebooting your TiVo to see if establishing a new network connection fixes the problem. If this doesn't make a difference, we will need to run testing to your TiVo. I'm not able to access your account via your Forum details, so I will send you a pm for more information. Just check the envelope icon at the top right of this page.
