atmaspheric | endeavors has a review of the EyeHome media player. It looks like a great networked media player, that is intented for Mac OS X. It uses rendezvous to locate Mac OS X computers on the network.
It shows photos from iPhoto, music from iTunes and all music files from the Movies directory in the home directory. It will play MPEG-1, MPEG-2, MPEG-4, DivXÂ¨, 3IVX and XVID video files and AIFF, MP3, WAV, (unprotected) AAC, Ogg Vorbis adn unencrypted WMA audio files.
The EyeHome has a native resolution of 480p, but it will scale to a higher resolution if you have a HD TV. One downside of this native resolution is that it will scale all photos down to 480 and then scale it back up to the output resolution.
Here are some screen shots:
