This is easily the best Media streaming server software for the Mac. I use it on a PS3 and it performs faultlessly compared to its rivals. All that is missing is native MKV which should be coming but in the meantime Yazsoft provide a simple workaround on their web site.

This software unlike the others is well supported both in terms of email feedback and also regular updates. For $15 this is excellent value for three licensees. Don't buy anything else when this excellent product does everything you need with a simple but great interface and works. No freezes, dropouts, unsupported formats etc etc.
