I assume you have already done a proper Forum Search for your model number in case other people have already answered your question ?
If so and that didn't help then check out this thread: https://community.sling.com/message/10363#10363
Come back if it that doesn't help either.
I am in Japan and am trying to get the Pixelia Prodia PRD-BT205 digital signal converter to work with my new Slingbox M2. I can get the picture and sound to output, but the device is not supported, so i cannot remotely change the channel via the IR receiver.
I know its a long shot, but is there another compatible device that i can set that the IR reciever can work with to change the channel?
