I bought the Roamio OTA 500 GB about six years ago. It's been great, no complaints, and it still works fine. I use it strictly for recording network shows, not for the streaming apps. I have two Minis in other rooms. Everything is connected by ethernet. I'm very happy with the TiVo system. TiVo has the Bolt OTA for a tempting deal. What would be the advantages/disadvantages of switching to the Bolt? I'm in a fringe antenna area; is the Bolt tuner better or worse than the Roamio tuner? Will the Bolt work with my existing Minis? Any other considerations? Thanks for your input.
