Would like to buy Bolt, but house is wired with coax

Hello - I received the offer from TiVo to convert my lifetime service (on my Series 2) for $99 if I purchase a Bolt. Would do it in a second, but I have coax running to two different TVs in the house from my Series 2. I really don't have the option of running other cables through the house, and I don't want to buy a Bolt for each TV. Any suggestions for having a Bolt and using the coax? Or am I just out of luck. Thank you.
