Problem with automating a home cinema system through a pronto with a HT200DM with interface cable. To pick up the inputs on the interface box and cable you have to press the AV button twice to get onto the second page. With the Sim2 remote this happens every time with no issues, but with the pronto the first page sticks and only with repeated pressing of the button does the second page come up. As you can imagine this makes automating the process very difficult, as the number of presses is not consistant. Can anyone help please
