The client device may be a portable media playing device (such as a laptop, Tablet PC, MP3 player, portable video player, or the like). By aggregating media content from plural sources (such as a desktop PC, a set top box, etc.) and providing a unified listing of the available media content from these multiple sources on the client device, a user can view all available media content at a single location, without making multiple connections to multiple different sources. Additionally, the user can pull media content from these multiple sources to the client device. Features also are provided to automatically synchronize, obtain, and update media content on the media source(s) and/or the client device. Various ways of handling digital rights management issues associated with copying at least some media content also are described. ## Claims ### Claim 1 A method, comprising: publishing data indicating available nearby media content stored in an original format on or accessible via a first nearby media source and a second nearby media source, each nearby media source being located on a local area network;
