All I can say is “w00t!”
Because several people have asked: I use a product called “PS3 Media Server” (PMS for short… go figure). You can get it at http://code.google.com/p/ps3mediaserver/ and more info is available at http://ps3mediaserver.blogspot.com/.
It’s written in Java, so it works with Mac, Windows, Linux, etc.
I just tell PMS what folder I want to stream, then that folder shows up on the PS3 to play from. So all the porn you’ve collected on your computer over time you can watch from the leisure of your couch on a ginormous TV if you have one.
Until next time...
