From a perspective that maybe hasn't been mentioned...
I know a number of private mailing lists that deal in the trading of static html tutorials, mostly art related. Often times they steal the images off some poor guy's site, copy & paste the text, and pass it off as their own work or never give any credit to the original author of the tutorial and graphics.
It is much too easy to do that with static html ones, and if your tutorial is any good at all, it will eventually be snatched by these guys. I have had a few original ones of my own 'snatched', that were originally created specifically for email distribution, that had been edited to remove any credit to me as the original creator and someone else's name attached instead.
With video, if you mark it properly, it is much more difficult to remove the credit, and people will know where it came from and where to go looking for more if they like it.
You might consider uploading to 5min Life Videopedia
if the video is 5 minutes or less. The site is strictly how-to videos and their player is unique in the way it presents them, specifically with how-to videos in mind. They will host it and give you an embedding code so you won't have to worry about bandwidth issues. You might consider breaking it up into segments if your videos are longer than 5 minutes each.
I posted about this site not that long ago, here: http://www.donationc...ex.php?topic=10415.0
Now if you wanted to distribute high quality DivX videos, you could go with Stage6
. They have a 2GB file size limit, and people have uploaded entire full length movies there. (great place to go for really old movies or indy stuff)
They also supply embedding codes, so you won't have to worry about using your own bandwidth to put it on your site. You can even start your own channel there for your content and customize the page for it.
I happen to like the quality of the videos on their site, and the fact that they let you download them, as well as watch online.
