I have a Marantz RC2000 and I was wondering if the Pronto could be programmed to handle input switching in a similar way to the RC2000. What I mean is that on my RC2K, when I hit the DVD button once, it just puts the remote in DVD mode, but if I hit it twice quickly, it switches my preamp to the DVD input. Can the pronto do this?

Also, has anyone had problems with the touch screen getting dirty and not responding well?
