I've spent the last 2 weeks trying to get my external satellite box to tune to channels from MythTV, but no matter what i do, the channel does not change (and my USBUIRT light does not flash, so it is not even trying to tell the channel to turn). My satellite box did not have a template, so I had to make one myself. I wonder if there is some setting that we are all missing in the device template when we create the device... Does anyone know, as mythtv is pretty much useless if I can' change the channels from any room.
I control my cablebox with a usbuirt. My setup is not working yet, but I am (I think) one step ahead because my usbuirt properly sends commands to the cablebox, which then responds by changing the channel.
1. Make a new template for the cable/sat box. Make sure you select IR control, not RS232 for example. When you get to the list of IR commands (on, off, 0, 1, 2 etc) make sure you select the correct IR device from the menu somewhere at the top of the page. This is important, and it is NOT always correct by default! Then update the page, after which you should be able to 'add new code'. You should have the remote REAL close to the usbuirt. Just keep the key pressed on the remote until LMCE pops up a window that says the code was learnt.
2. Go to AV devices, select your cable/sat box, and make sure that here, too, the correct device is selected for controlling it! If not, correct it, update/save the page. BTW, you can always get back to the IR codes by selecting A/V properties, on the right.
3. Go to advanced, click 'send command to device'. You should be able to select a command from step 1, for example 'off'. Make sure to get feedback on the command (little checkbox), and then send the command. The usbuirt should flash, your box should turn off, and the windows should say something like 'Command received OK'.'
Does your setup work to this point? Let me know if there are problems so far.
