I bought a refurb from tivo.com for my mom this summer. It ran out of guide data last week. The daily calls have been failing with "Could not connect". I've rebooted it. I even picked up the phone to make sure it's dialing out. It is dialing and I can hear it attempting to connect but it stops with the "could not connect" error after several seconds. On a couple of attempts, it never dialed. I brought it to my house and connected it to my network and it dialed out successfully over the 'net. My guess is bad modem. Are there external modem kits for S2 machines? She's only six months into the 12 month agreement, so I don't think getting a new machine is an option yet. Any idea what the cost to repair it would be? Thanks!
