I've consistently had problems browsing to some of the content being served by PS3 Media Server. It seems to be the case that if the depth of the tree exceeds a certain size (I think it's 8), the PS3 won't let me descend further into the tree. The same content stored in a shallower tree is served without issues.
Is this a client-side problem (i.e. a limitation of the PS3 UI) or it a problem with PS3 Media Server?
In either case, how can I work around this? I can't see an obvious setting for this on either the PS3 or in PS3 Media Server's configuration settings.
