was never able to get mediaportal remote to work. i installed the plugin from the site and installed the remote on my phone (htc evo). after starting the remote from the phone and starting the program ,nothing happened. i ensured my ip settings and port configurations were all correct, ram again, even un and reinstalled the program, no luck.
i got fed up and installed Unified Remote from android market. Ive tried a couple of remote control devices since, but it is by far the best. there is still point and clicking, but the versatility it showed is worth it for the remote\htpc experience. as matter of fact, i´m using it to post this right now.
