It's not that I've looked all that hard, but I know that when I first got into video, I searched quite a bit and never really found much. Unfortunately, your query is fairly open-ended.
I recently had someone ask me if I could make a video showing the process that I used and I kinda rudely replied that it was a tall order for such a request. In a way, it's kinda like asking for the history of the US in a two sentence request. It's not that I'm not willing to help, but to put together an instructional video isn't something that I can just sit down and 15 minutes later post it onto the web...it would take hours and hours to do a decent job of editing it all and since I'm an engineer, there's a certain amount of perfectionist in me that would want to make sure it's fairly pro quality if my mug is gonna spread over the internet with something like that.
Anyway, getting this response on point, I don't know of any tutorials out there. I found that learning the video software wasn't as intuitive and simple as many software packages, but most all of the video editing software has the same basic features and concepts. So, once you get one and start understanding the basic concepts of working with the software, you should pretty much get a feel for all of the packages.
Having said this, I've only really worked with two or I suppose I could say three; Premier, DVD Lab Pro, and ...ugggg...I can't remember the name but the worthless piece of shit product that was put out by Pinnacle...stay away from that.
Premier is the workhorse, but it takes some time to learn. I found DVD Lab Pro to be really easy to use and within about two hours I was up and fully running. There is a rudimentary tutorial that goes with it that shows the basics of putting together a video. The tutorial really is basic, but effective in getting you out of the starting blocks and going from a standstill to fully running in a very short time.
If you want truly professional looking video's, they are possible with DVD Lab Pro, but frankly that product is a step down from Premier. Adobe Premier truly enables you the ability to produce first class video's that look like they came straight from the pro video editors toolbox.
Frankly, while the features and the power of Premier is second to none, I love the ease and totally functionality of DVD Lab Pro. I know it's not all that popular amongst the video people out there, but I tape alot of stuff off of TV (shows like ACL and other PBS music performances) and there's nothing like being able to put together a VERY nice DVD, complete with menu's, chapters and the whole nine yards in little more than 10 minutes. Yeah, it takes maybe 1/2 hour to compile the DVD, but I've got so many templates made now and saved onto my harddrive that it literally only takes me 10 minutes to edit and create many of my DVDs. Just can't beat that, IMHO.

PS: Obviously, I take far more than 10 minutes designing many of my DVDs, but for those that I just want to copy the basic design of an already produced DVD, such that the menu's have the same format, the same bullet styles, the same locations of titles, etc. this is all it takes.
