I just discovered this feature a few days ago when poking around in the mediaportal options. I was rather surprised to find that when I enaled the option to use direct imput, it had a drop down menu and my logitech dual action was listed. At first I had problems which I thought were do to bugs relating to direct imput but then I figured it was just problems playing files that were in a folder which a lot of files of the same tiype such as music. Thankfully, the problems got ironed out. I don't know how I fixed the problems but they are fixed and have been using my gamepad to control mediaportal ever since. I mapped previous/next item/chapter to the buttons and they have been working great.
