There's a card pairing option in Openbox. You need to search Google for "Card Pairing on Openbox". You need to edit certain settings when you insert your card in cam slot. However, it is possible that your smartcard might get locked. Sundirect card pairing was successful on my Openbox S-10 so technically speaking, it's possible to use d2h on Openbox which uses Irdeto 2 compression. Please do this at your own risk.
