I'm glad you got it working.
I assume you mean you want to generate the xml file manually. It can be done, but it's not recommended because of it's complexity. Here is the XML generated from Personal Video Database for tha Avatar trailer.

It depends on how much information you want to see on the screen. I guess the minimum would probably be <Title>, <Path>, and probably <Poster>, although it will run without a poster. This is a good example of why I like to use third-party software to generate the XMLs. You get all of this good information, and it does it for you automatically. Some people have complained about having to install third-party software, but I think the benefits are worth it.
You could probably get by with this, but I haven't tried it.
I've made a few bug fixes to roksbox, and I'm getting ready to release a live demo with several movie trailers, some music, and some photo slideshows. Hopefully I will get that ready this evening. First I have to figure out how to deploy a version update to the private channel.
I'm also making it so your media files can reside almost anywhere.
If you have any more questions, please ask.
