I’m having similar problems with my setup. I’m getting audio, no video, over the firefly stream and would appreciate some help.
The video was encoded in handbrake and works fine on iTunes and on my iPod and iPhone, but doesn’t stream well.
Here are some other specifics:
The Server is Windows Home Server with Firefly SVN-1586
The Client is a MacBook Pro with iTunes 7.6.1.x
The file is
MPEG-4 video
Bit Rate: 159kbps
Low Complexity
Res 640×368
Codec H.264
