The new software only went out to about 400 people, so many have not tried it yet.
For me I got the update and my DLNA is working.
Now I just got to choose the best DLNA server software for my needs.
I posted my thoughts in the huge DLNA thread thats been on here a while, but in case others don't want to go through it, my thoughts (in a nutshell) are:
TVersity and Serviio worked the best for me. TVersity has a unique feature in that the DLNA server can stream your video to an internet web browser which is nice because you dont even need to use client software and if you have a public webserver in your home (like I do), you can stream your own videos to yourself over the Internet. I ended up going with Serviio however because internal media was more important to me. My entire media library was created with the intent of being used in XBMC, so EVERYTHING I have (8+ Terabytes) is already scraped for XBMC, and Serviio is the only DLNA server that can read XBMC XML data.
Serviio also has a nice interface that is compatible with Windows Home Server 2011's dashboard. Even if you are not using WHS2011, it has a nice config tool that allows you to assign profiles to specific IP addresses on your network, whereas most DLNA servers rely on auto detection.
PlayOn is a nice package, but it was originally designed as a web streaming service. DLNA capability was recently added and is still in beta, so the featureset is not rounded out as much as with Serviio or TVersity.
Plex Media Server is another option which has what looks to be an excellent feature set, but like PlayOn, DLNA capability was recently added and has a lot of bugs. There are very few profiles for devices, and the majority of devices require trial and error manipulation of an XML file. Another nail in the coffin for people like me who run servers, is that Plex cannot run as a Windows Service. This means that it requires a user to be logged in at all times to get the program to stay running. All 3 other options (Serviio, TVersity, and PlayOn) can run on a server without leaving someone logged in. There is a huge thread on the Plex forums where people are requesting this functionality and offering workarounds. None of the workarounds work well, however, so until this feature is actually implemented, Plex is not an option for people with actual servers in their homes.
