I have a bunch of video files on my iMac that I like to stream to my Xbox360. Prior to upgrading to Lion I used an app called Rivet to stream and it worked great. Rivet does not work for my running lion and I'm not sure why. It is not a ppc app that relied on rosetta, it loads the app fine but no longer streams. Does anyone know of another app that will do this or how to make rivet work again?
