Hi im looking to buy a Venton Unibox Linux HD2

I only have 1 Sat dish installed. Would the Venton Unibox HD2 1x Satellite DVB-S/S2 - Twin plug and play tuner option be enough for a twin cable coming from the LNB?

Basically so i can record and watch a different channel at the same time.

Just a little confused with all the tuner options

Thanks
