The PS3, however, shows the infamous "incompatible data" message. I found out that the PS3 does not even support MP3

The Twonkyvision homepage offers two precompiled binaries, one for Windows one for Linux. None for Mac OS. It further states to put the lame plugin into the cgi-bin directory of the server.
How can I do that with my Mac (Leopard 10.5.2, TwonkyVision 4.4.4)? Or, more concretely:
1) Where can I get a precompiled lame plugin for Mac OS X?
2) Where is the cgi-bin directory of the server??
3) Did anybody manage to stream MP3 to the PS3 from Mac at all???
Any comments appreciated.
