Phoenix32,
Based on what I've read online, I think I may have a solution (or at least point you in the right direction)... but I can't test it since I don't have any DLNA recievers.
Basically, you would just have to use Putty to get into the GOS via SSH. That basically brings you into the operating system where you might be able to install miniDLNA. Mind you that I am SURE doing this will void any warranties
The DLNA server I would use would be miniDLNA which is written by a Netgear employee (open sourced). Installation steps can be found here but it was written for the RedHat/CentOS/Fedora packages... I am sure SUSE isn't that much different but certain dependencies may need to be installed:

If I do come across a DLNA reciever, I would definitely probably try this out... btw the installation instructions are a bit dated since the latest build of miniDLNA is version 1.0.22. Good luck!
