The PS3 media server shows as a device but fails when selecting a folder. So sharing the public folder i get the initial data folder, but after selecting data I don't get the video,audio etc folders. I also tried to share the video folder directly but got nothing.
Sounds like the PS3 media server is doing something mildly out of spec when returning the path to folders. Unfortunately we do see this more often than you'd imagine for what should be a 'standard'.
If you can give us access to your system and the PS3 the. We may be able to do some forensics on what happens when we interact with the server and detect what's failing. Let me know and we can the. Let me know then we can fix a time to take a look.
All the best
