Some DLNA/UPnP players, such as the PS3, are not visible on a home network and cannot be detected by Skifta automatically. You can still use Skifta to play on these devices however. After selecting "Play on unlisted player", Skifta connects your selected media source to all DLNA/UPnP devices on your Wi-Fi network. From here, select the PS3 or other unlisted device and look for any media sources labeled "Skifta" under music, video or photos. Use the device controls as you normally would - e.g., use the game controller on a PS3 - to find and play your desired media.
