Recently (last night) a lightning storm zapped the modem in my RCA Series2 DVR40 TiVo. It can no longer dial out. The DirecTV rep wanted to replace it with a DTV DVR unit but I prefer Tivo. For now, I won't be able to order PPV, but more importantly, he says, not get software upgrades from TiVo. Eventually I guess this will disable the unit entirely. What are my options? Is there a regular MB in there that I can possibly replace the modem myself? Can I buy a new TiVo unit directly from TiVo and purchase my TiVo Service from them? We have 3 other units from DTV, one is DVR, one has no recorder and one is also a TiVo (HUGHES?). Any help appreciated.
