That's pretty much correct. The steps are: 1) You tell the mythtv frontend that you want to change channel. 2) The frontend tells the backend, which calls a channel change script, which you have provided. 3) The channel change script either uses lirc to drive an ir-blaster which mimics your remote control to change channel on the cable box or sends a code via a serial interface to the cable box (if your box has a serial input that is). 4) Assuming the channel change script completes successfully then mythtv will register the change and select guide information to match the new channel accordingly. _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
