I can't help you with the media player on your page because I'm not a DJ.  I can help with customizing your profile though.  If you don't know anything about HTML the easiest way to customize a profile would be to find premade layouts.  So you'd just do a google search for "premade layouts".  The site I use the most for premade layouts would be www.whateverlife.com.  Lots of times you will see them called myspace layouts, they work the same in RLC. Once you find a layout that you like you just copy and past the HTML code into your "about me" section on your profile, then click save changes.

There are lots of sites like the one I mentioned above that has profile generators.  Those basically allow you to make your own layout without knowing any HTML.  You just find a picture that you want as your background, upload it to a site like photobucket then follow the steps in the layout generator.  Once you've made all your choices you just copy and paste the code into your about me section like I said before.

There are a lot of DJ's in world.  Maybe they could help you with your live stream. You could also go to http://www.rogues-fm.net maybe you could contact someone on there that can help you.  I know they DJ a lot of parties and stuff in RLC.

Hope this helps.
