From memory the Wetek Play came in Dual DVB-S2 or Single DVB-T/T2/C tuner versions (the T/T2/C was a single tuner capable of all three standards)?

Ah OK i thought they were all twin tuners from this page on here https://wetek.com/shop

Was going by : http://openelec.tv/openelec-box where only the DVB-S2 is detailed as dual, but the ATSC and DVB-T/T2/C aren't.

Clicked on your links and if you look carefully at the the two RF connectors they are labelled RF-in and RF-out on the ATSC and DVB-T/T2/C models I think - with the DVB-T/T2/C model being a combo tuner (tuning either DVB-T/T2 OR C but not both at the same time I think)
