Advertisements I've had a roamio with a couple of minis using verizon fios for a couple years now. It's been working perfectly with no issues until very recently. In the last month or so, it has started to get flakey. First, very rarely and on just a couple channels. Now it seems to be happening more and more frequently and on more channels. Is this indicative of a FIOS/signal problem or a TiVO problem? How do I diagnose this? I'm guessing that they'll each point the finger at the other guy.
