Passing variables to real media

Alright gang, let's see if you can help me with this one. I'm coding a media player for my website, and I've completed the windows media version, however upon attempting to do the same with real media, I'm having problems. I need to know how to pass variables from javascript into the embedded real media player such as the song title, artist name, as well as some of my own variables from my code. If any of you guys can help me out, it'd be greatly appreciated!

Specifically I'll be passing the variables from the real media .asx file being accessed by the real media player into javascript to display them on the media player page. I found a few commands that should do this, but they seem to be for an older version of real media. Please help me, Dev-shed kenobi, you're my only hope!
