For me I am getting the video is denied messages on the actual YouTube pages although the first link from here worked.

Hmmm...I was able to see all of them. I'm not sure I clicked on them all but the ones I did worked fine.

The Leopard intro movie Apple usually doesn't implement a new one until around the final build. If I remember correctly, all of the Leopard test builds had the Tiger intro movie up until nearly the GM build.

I've enjoyed these.

Yes ..it breaks a potential NDA but these are just small touches that won't even be covered at WWDC most likely.

Besides, there's nothing useful or remarkable.

Controls in the new QuickTime window client area are really pitiable when watching small size clips.

The performance will hopefully impress me more than all that.

Hmmm i'll have to pull up a small clip and see how the controls are affected.

I like the simple substitutions and cleaned up services menu.
I'll probably use Spaces more in Snow Leopard especially now that I have a 28" LCD.

I think these videos are only scratching the surface but then again Snow Leopard just doesn't have any whizzbang features and I really think Apple should be targetting a $69 price point.

I hope they deliver a Mac Box Set with Snow Leopard for a great price.

Isn't anyone going to say the obvious? Most of these videos cover features that have been part of Windows / Office for an extremely long time.

Wow. A video that shows the Put Back feature. Sorry, not impressed when that feature existed in System 7, 8, and 9, and should have been in 10.0.

So it shows off a pretty interface. The main point of Snow Leopard was to offer better optimization for Intel Macs. That is what people want to see. Since it is only a developer build, it is not yet fully optimized in itself.
