[mythtv-users] Hauppauge 2255 dual tuner?

Greetings,

I own a Hauppage WinTV-HVR-2255. It claims to be a dual tuner and thus be
able to record two shows at once [1].

I can successfully record one show at a time, but am wondering about any
configuration changes or pitfalls for dual recording.

Has anyone had success recording two shows at the same time with Myth with
the aforementioned hardware?

I'm running a pretty old version of Myth...

0.27.5+fixes20151228-dmo1

Here are some snippets about my tuner hardware from my system

lspci fragment:
02:00.0 Multimedia controller: Philips Semiconductors SAA7164 (rev 81)
        Subsystem: Hauppauge computer works Inc. Device f111

Does anyone have any thoughts, hints, or advice about dual recording?

Thanks!
