To quote from SubJunk on the PlayStation 3 Media Server v1.50.1 Build 61 changes:
This build functions as the bleeding-edge testing version of PMS. Here you can find features and bugfixes before they are added to the official version, and sometimes ones that never will be. Using this build is mostly a way for you to see the newest developments and to help us by providing feedback.
