OK - I misunderstood you. That's not a setup I'm familiar with. If I understand you right, you're saying that when you change channel on your cable box, then a different channel comes out of the output as channel 3? In this case you shouldn't be feeding your cable output input into the S-Video input of the PVR, because S-Video doesn't support tuned signals, it's just a raw video input. So I guess you feed your cable-box output into the co-ax/cable input of the PVR and, in mythtvsetup, you just give every channel the frequency corresponding to that of channel 3. > > 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. > > > How can it get new guide information if the tuner card is still on the same > channel (3). Well myth will have guide information for every channel, and it will think it's changed channel but, because they all have the same frequency, it will still be on channel 3. That's where you have to run a channel change script to actually change channel on your cable box. If I were you I'd Google for the make and model of your cable box, and you'll probably find someone has been there before. I must admit I'm still not quite sure I understand your setup, so I'm guessing a bit (a lot actually). Good Luck. _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
