Dynamp run well with Winamp3... but Winamp is big monster... and doesn't interact friendly with the system. It smell like a lot of "bidouilles" in Winamp3. Of course, Winamp3 looks better than Winamp2, but what does it do more than his brother ? Video ? When it's work !...

As I said, you can use dynamp to control Winamp3 and there's no problem except that Winamp3 is the problem. But you are very limited with Winamp3.

So, listen DeViLbOi and switch back to Winamp2. You'll could do everything you want with geekamp, lsslider... It's easier to integrate Winamp2 perfectly in your theme.
Have fun and read the docs. There's nothing special to make it works. Just read.

Note to all newbies:
If you wanna play with Litestep;
Then you have to read a lot;
