From what I have read around, DVB-S 2 uses a different signal encoding method. The Current Satellite Digital TV encoding uses QPSK (Quadrature Phase-shift Keying), where as the new encoding method will use 16QAM (16 Quadrature Amplitude Modulation). This new encoding will mainly be targeted at 2-way satellite communication as it will potentially allow at least twice the data rate of existing systems for a given transonder, where as for TV transmission it will allow a capacity increase of about 30%.

I haven't come across any such satellite receivers, but then again chances are that there are few (if any) broadcasts using the new DVB-S 2 system.

The following article I came across gives a few details of DVB-S 2:
