As far as firmware I updated it last back in December, but haven't bothered applying the latest update for the audio issue because even though I get it and I'm very happy they fixed it, it's more of a hassle to unplug everything and move it around than it is to just deal with it.

The brand of TV honestly doesn't matter since the TV isn't affected by any of this. Same deal with the remotes, I'm not using any codes, I'm just using the default remotes provided and none of the buttons used have been changed from their default settings. There also isn't a cable box anywhere in the system. This is purely an issue between the TiVo remote, the 1070 remote, and the 1070.

As I said, it's probably just some weird intereference and not something fixable, but it's certainly odd that it was a repeatable phenomenon.
