Karl Taylor's DVDs are great (and there are free videos on the site as well). I've reviewed them for friends who are new to photography. There's no outright misinformation, and there's a lot that transfers across genres. They're not particularly cheap, but I'd say they're a decent value (especially if you can split the cost among a few people).
Some of the KelbyTraining course videos are very good as well -- and some are really not so good. The ones I've seen with Jack Reznicki as the instructor (One Light Lighting, Photographing Children), in particular, are worth the trouble. Others have been a complete waste of time (or maybe they just covered something I think should be so blindingly obvious that spending an hour explaining it over and over again just seems like a waste of time to me -- I don't have the advantage of actually being a neophyte).
If you're into studio portraiture, you can always cruise YouTube for name brand professional product videos. If you ignore the sales pitch aspect, there's often a lot of technical goodness to be had -- remember, these people want you to keep buying their stuff, and the only way to do that is to show you how to make the best use of it. Elinchrom's product videos, for instance, are great even if you don't plan to buy or use any Elinchrom gear.
