So, I was just trying to find some information about how to configure other VST instruments for Sibelius 5, and I found this handy little tutorial from Daniel Spreadbury of Sibelius about using VSTs and AUs. This could act as a great compliment to Jim's video tutorials.
Don't worry, the web address is only weird looking because it was originally a webcast hosted by adobe.

I actually was going to post the same thing! :)
I checked this out a couple weeks back and it's a great little video. Gives a nice overview of how Kontakt Player and VST's fit in with Sibelius 5. I'd highly recommend it to everyone. It definitely helped me understand the process more completely.
