i am having similar troubles. i took a look through the forum, and this sounded like the closest to my own problem, so here goes.
i have pms, built from source files, running successfully on a centos 6.4 home linux server i just tossed together. my PS3 is
recognizing it just fine, playing music off it with ease.
but not a single one of my 3 win7 boxes can see any music to play in WMP; they seeee the pms server, but they see absolutely no content in it at all. perhaps a little more info: i have a working samba setup on the server, which the win boxes are happily working with, so the first thing i tried was to move all the media server media onto that big open samba share. this lets me play songs/albums(.mpu) fine from a windows explorer window, but WMP simply cant see any content in the pms media server still when i try it that way.
any ideas? could it be a owner/group/permissions thing? could i just be cursed? help a fellow tech weenie out, couldya?
