It actually was intended for use, it came from patches based on linuxtv.org/hg/~stoth/hvr3000 2 years ago, for this exact reason. The idea died on the vine, except for a few die-hard people to maintained their own spin-off/derivative. > > I like this approach. So do I, it solves a lot of problems with multiple frontends on a single transport bus. At the time I did not patch the 7134 framework with the minor changes for it to comply, but if that's done then the 6-in-1 7134 Dual DVB-S/T/Analog card would also benefit greatly. Right now that card only supports some functions in the kernel (IIRC). It's been a very long time but this was also mentioned on the mailing list. - Steve _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
