stumbled upon this over on dvdrhelp.com, and I've been really enjoying some of these tutorials. They are all based on adobe products, so if you use encore, premiere or premiere pro, these are some great instructional videos that you can download for free. They cover beginner stuff and also some more advanced topics. If you are just getting your feet wet in video editing (like I am), you might find this very useful.
