After months of headaches with MediaLink and Rivet since upgrading to snow leopard, after TwonkyMedia generating tones of crapy databases using 40GB of my hard drive while not being stable, I finally found the solution to stream to my PS3: PS3 Media Server.
It runs smoothly, never crashes, and just does its purpose! Simple
Its amazing to see how free, open source, softwares regularly outpaces their commercial counterparts.
In one word :
for your great job!
