streaming dlna from fedora to a Samsung TV (mediatomb)

I was trying to get my Samsung TV to play files from my Beefy miracle box and although it was able to connect, it would not show any files. It took a bit of hunting around but I found the following patch needed to be applied to get the files to display.

Next I needed to recompile mediatomb on fedora, to get that to work I had to modify the rpm and add another patch.

After applying that patch the package will build. You then need to change the config.xml and set some headers so that the Samsung will see the server.

After that, my samsung was able to see the fedora box and successfully stream files, even SBS 3d files work properly.

Here is my compiled rpm for f17 and the src rpm.

mediatomb-0.12.1-22.fc17.x86_64.rpm mediatomb-0.12.1-22.fc17.src.rpm

Here is the complete config.xml
