Has anyone here gotten it to work?  I had it working soon after I first got my PS3 and loved it, but it stopped working about a month ago.  Now it's like my PC can't even see the PS3.  I don't know if this is the place to come to for technical help or not, but I've looked around on the internet and I can't seem to find any advice for getting it to work again.  If any of you guys have had this problem, I'd really appreciate any advice you could give me.

Thanks!

What OS are you running? Vista OR XP? vista all you need should be there with XP you'll have to download WMP 11.

In vista click start/control panel/network and sharing center. in the sharing and discovery area click media sharing at the bottom click change sharing settings tick share my media to:
and you should be able to figure it out from there.

Yeah, that's what I did originally and it worked fine.  Then one day I turned on my pc and it couldn't see my ps3 for whatever reason.  I have been able to do media sharing since then.

Cool, I'll try that.  Thanks

Is there any use of doing this if

1. My PC is connected with the HDTV so I can watch the movies in the correct aspect ratio
2. My external Hard disk is connected with my PS3 so I can watch Divx movies, play music, and browse through photos from it.

Is there any other advantage? In my room my HDTV, desktop PC, and sound system are setup. And I know that I won't be moving my PS3 from that spot because I like to play it on the HDTV. (Young siblings are happy with their PS2 and Xbox)

Download PS3 media server for your corresponding OS (google it), and have fun!

I had the same problem as you. One day the sharing just wouldn't work. I tried several programs with no luck at all.
But the fix for me was only to reinstall WMP11, and the media sharing have been working fine after that.
