5045 stereo tuner?

I’ve looked around and can’t seem to get consistent information about the tuner in the North american version of this box. Is it stereo or mono? Some revies/specs say stereo some users say mono. Can anyone with this box put the mystery to rest and tell me if the tuner is actually NTSC stereo and you can record in stereo from the RF connection? I’m not really interested in the EU version as the tuner is probably different.
I’m about to buy this box today but the mono would be a deal breaker for me.

it’s stereo
