I have downloaded the new firmware for Slingbox pro HD. My remote is a humax RM301, which is not to be found on the standard lists so I have a custommade remote which I found on this forum. Previously this remote worked fine although I could not acces recorded items on mybox. However, when I now try to install the custommade remote following the instructions in previous threads, there is no way to find "custom" in the list of devices. What to do?
