Hmm I couldn't figure this stuff out. I put the files in my root directory and named one of them "default.xsl".. Now what? I browse to my root directory and things still look normal. When I open the XSL files in my browser I see the pretty pictures and some things that look like table headers, but that's about it... Plus some messy looking stuff like:

Tags Tune ?.m3u ?SERIAL=%23.xml Tags Tune

I guess the idea is to show the directory listings in a nicer style, but it's not working for me.. Must be doing something wrong.
