Have a Mac, but having trouble getting stuff to stream onto your PS3? If you haven't tried Nullriver's MediaLink solution, you might want to give it a shot. In addition to streaming content, it shows album art and preview screens on your PS3 for a multitude of formats. There's support for iTunes integration. MediaLink lets you organize your folders however you want as well, so it's a bit more flexible than other programs that often get recommended for streaming. It's not without its shortcomings -- people are having trouble with AAC and M4A formats, but that's something we're sure a few people don't really care about. Give it a shot, let us know what you think.
