Thanks. Can you publish a preliminary datasheet for the Demod, or a preliminary GPL driver for the demod yet? That might help. What I/F frequency does the demod need? I suspect the 2131 driver is fixed to match the demods it's been implemented against, and will probably need to have the I/F determined during dvb_attach in the mt2131_config structure. The MT2131 driver's pretty raw and support for new demods will grow over time, it can be easily extended to incorporate your demod's needs. - Steve _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
