I've stumbled onto a couple problems with this method, may just be my computers though?
If I turn on my htpc before the fileserver, the media server which auto starts with windows gives a bit of an error saying it cannot connect to the library (on the fileserver) and brings up a prompt asking what to do. At this point my fileserver is already up an running and the jriver server app is running but the htpc just stays stuck at the library prompt.
Would be nice if it would just keep retrying in the background or just default back to the server process and try again when a connection comes in like from the gizmo.
Another thing that happened twice now (though I don't think this has anything to do with the jriver software).
Tried connecting to library from gizmo and nothing. Logged into fileserver and noticed a popup saying jriver didn't close properly last time and gave a few options like reinstalling, redoing something with the library. My filesever is set to go into hibernate after a certain amount of time of inactivity so not sure if that is causing problems.
And lastly gizmo or one of my library servers froze up a couple times when using the track forward button on gizmo, possibly just a computer problem.
Other then that awesome so far.
