There's Adobe tv....and have you tried YOUTUBE?...its full of them!
How do you hope to use Photoshop? Photography? Illustration?
As advised Adobe TV has some of the best as you'd expect. Try Google with Adobe TV Russell Brown, or Julieanne Kost.
Try Kelby TV for Scott Kelby and the Photoshop Guys. They are the best, and I suspect had input into making the Photography Bundle deal happen.
There literally hundreds of top quality video tutorials here http://kelbytv.com/
A couple more
The problem with YouTube is that there is so much utter crap. Everybody wants to do Photoshop tutorials, and while some of the people are kind of OK with Photoshop, the production values are appallingly, cringe making bad. Heck. What am I talking about? They are MUCH worse than that.
But there are little pockets of pure gold, like Donny and his ‘You Suck at Photoshop’ series.
And just to get you going, I give you #1
I can't give you Donny without telling you about the infamous 'Vanishing Point' video. Appart from being very funny, it is actually really clever.
