I see a lot of the same questions constantly come up on the Gentoo Forums and on #gentoo about how to do some stuff with multimedia, ranging from basic to advanced topics. Most of these are already answered and come up on a regular basis.
I'm not claiming to be a multimedia guru, but I have run into a lot of simliar situations and played with a lot of applications, and get tired of seeing the same unanswered questions over and over. :) I'm going to write up a FAQ that should hopefully field the more common questions.
Instead of rehasing HOWTOs and tutorials, I'll have a mix of quick answers, keywords to google for, and links to detailed tutorials. Also, I'll be trying to cover the concepts and principles instead of providing detailed explanations.
I've listed below a few of the ones that I already plan on answering. If there are more that you can think of (keep them simple and short, please) drop me an e-mail at beandog at gentoo dot org.
