A better way to fix it would be a Tivo App for Apple TV.Apple removed the ability to AirPlay just the video content from the TiVo App when streaming to an AppleTV from an iOS device in iOS10. This ability was great because it allowed you to stream content from an iOS device to AppleTV and then use the Siri remote to RW and FW the stream.
The only option now is to use AirPlay mirroring in iOS10 which scales the video resolution down and doesnt allow you to use the AppleTV remote.
Appears the only fix would be for TiVo to add an explicit AirPlay feature in their app.
Can TiVo please do this
