HD Homerun tuner usage

I have a two tuner HD Homerun connect. If I have a show set to record can I also watch it live while recording another show? Or does watching the show while recording it take up both tuners? I would appreciate anyone's experience with this situation. Thank you

In the app you can set Tuner Sharing to On. Then if you're watching and recording the same thing, only one tuner will be used.

Found it, and switched it to on. Thank you
