If you ran into the segmentation fault message you need to follow this step. In Xterminal type the following commands. sudo gainroot apt-get remove --purge rygel reboot It will remove every components of rygel and then reboot your system. Then back to app manager and reinstall it After you've done so, to go Xterminal and reboot once more to be sure. After rebooted, type "rygel" without quotes and leave Xterminal open until you stop using DLNA. If you closed Xterminal, Rygel will stop working. Hope this help.
