OK, I don't think the patch to kill "orphan/child" processes is working properly. Check out this screenshot of my task manager. It's taken after a movie is finished and I'm back in the filesystem/PS3 dashboard/"browsing" view.
Edit: The above is taken from the most recent Community Build which was posted a few hours ago.
Edit2: I think I know why. It's missing the following file (taken from my log)
[Thread-50] INFO 23:29:30.444 -- Exception in thread "Thread-50" java.lang.UnsatisfiedLinkError: Can't load library: C:\Program Files (x86)\PS3 Media Server Community Build\winp.x64.dll
