strmkr,
Hey man I've been having my own problems with it. I do stream Real Audio from my bands webpage but I'm in the process of learning to stream mp3's. Saves time for people trying to give a listen. But you know that.
You might take a look at my thread down the page a bit,"Good storage space for my Mp3's". If you follow all the responses there may be some helpful suggestions there for you.
I play in an R&B band and I have links to a couple of songs in the first post. Should you decide to take a listen, as you will gather from the responses, my Mp3's are not without problems. They will be very long downloads depending on the speed of your connection. I'm not going to mess with them however until I'm ready to stream.
Good luck,
Rusty K
