PS3 Media Server on Amahi
DRAFT in progress by Greg Martin (uslacker)
Introduction
Amahi supports several applications for streaming content over the network using DLNA. PS3 Media Server (PMS) is different in that is was designed to transcode video files on the fly so they can be played by the Sony PS3 as it supports a limited number of video & audio codecs. As PMS matures, it supports a growing number of devices.
