We bought our 320 GB Media device in Jan 10, In April the device started having problems in that it will no longer detect Channels via the antenna although if we plug the aerial directly into our HD TV the TV works perfectly. We contacted TIVO (have an case ID) and have been working with them to find a solution since April 13 2010. Now its July dispite my repeated requests to exchange media devices TIVO still have not approved or agreed to the exchange. Feel that we are just getting the run around. Can anyone help with suggestions to speed up the exchange process or advise what recourse I have against TIVO.
