Some of you folks may have already seen this posted over at DMN but my site www.luciferjones.org has 5 Vegas tutorials on it covering everything from editing basics, through compositing and keyfrmaing to surround sound. All of which are also availible as PDF downloads.
There are also a collection of other useful resources, tutorials, reviews and such stuff there on wider Video and digital media topics. Just go to the RESOURCES page and select from the drop down list.
Hope someone finds them useful.
Cheers
