Right, test report coming:
The Procaster app is really simple and effective to use, allthough it didn't recognise my tv card and there are no configuration settings to help with that. You just click a few buttons and you're up. The gamecasting feature is awesome and you no longer have to play with adjusting your lfs window so it's just the right size for the cast. I'm sure this will now be used for the majority of lfs broadcasts since it's such an effortless app.
However something is missing: Maybe someone forgot that you have to be able to capture audio as well as video. There are still no solutions for that, but I guess it's kind of pointless anyway since most soundcards nowdays support stereo mix.
