I'm using the analog output (composite jack) on my soundcard to go
straight into my stereo receiver. My master backend/frontend
machine is an AMD Sempron 2300. Here's the output from mplayer::<br>

<br><br>can you paste the stream info for the firewire captures from mplayer's output?<br>are you using the analog output of your soundcard or passing the digital<br>audio through to a receiver? whats the cpu/speed of your system?
