Big boss just released a mobile substrate extension that allows you to display any app on a TV screen. It works great so far, however it is a work in progress. From Big Boss: Support for the springboard is currently disabled and there is no landscape mode. They also said certain Open GL apps like Google Earth might not work. I've been playing Silent Hill all night, because it is displayed in portrait mode. The hack has a great little app to toggle on and off the apps you want displayed. Check it out under the big boss source. I have only had one problem with it when safari stopped displaying. A simple restart fixed that.
