We have the DTV_FE_CAPABILITY_COUNT and DTV_FE_CAPABILITY (current defined but not connected in dvb-core) which would be the natural place to expose every older (and newer) feature of the demods. The command you're referring to now does exactly what it's supposed to, it selects your last SET value (or if the demod has provided a .get_proeprty() callback), the demod could chose to answer differently. In principle we could add a one line fix to the cx24116 demod "c->delivery_system = SYS_DVBS2;" to solve your initial problem - but I don't that's the correct approach. When the phase #1 work is done we'll fill out the capabilities changes in dvb-core and start to expose interesting features, like LNA, diversity, delivery systems, power controls or anything else that the linuxtv community thinks is generalized and useful. We will take these steps carefully. - Steve _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
