I just realized I forgot to update the partition branch with the previously mentioned items. It now includes those features as well.
Additionally, inspired by ashes experiment, the server will now make sure the media requested actually lies within the tree you've designated as your music folder. This is very primitive security but it will prevent some of the more obvious abuses. Still, I recommend that this software only be used behind a router and on a trusted network.
I'm trying to figure out how all of this stuff works so I can contribute. As a first little test that I can change something and update the client properly, I changed the "screen.SetListStyle" from flat-episodic to flat-category and the side poster art now displays.
Are the fixes for the numeric folder names in the partition build or is that still to come?
* video must be encoded in one of the supported mp4 encodings mentioned on page 37 of the Component Reference in the SDK documentation you've all downloaded (Handbrake's Ipod setting with "Web Optimized" checked works.)
FYI: Handbrake's "High Profile" + "Web Optimized" also seems to work.
