Sonic Foundry were recently bought out by Sony Media, so their excellent Vegas Video software is now rebranded by Sony.
If you have not yet checked this package out then I can highly recommend you do. The video editing is presented in such a way as to enable a novice to easily learn it's most basic functions and with a little help from the built in tutorials you can quickly get very hands on with the most advanced features.
Also there the DVD architect which is actually really good and it's my preferred DVD creations software at the moment. I used to use ReelDVD and while some of Reel's features are not available in this package (specifically, multiple sound tracks) I'd be happy to lay a bet that the next version will have it.
