Apple always posted a lower quality (SD?) broadcast first. I think this stream also adjusts its quality based on Apple's bandwidth (since tons of people hammer the server). After 24-48 hours, there's a HD link added next to the SD link.

Just chill.
 
Update

Download the podcast.

I did it a few hours ago, and while not HD, it sure looks great compared to the stream.
 
only prob is the res is so low that all almost all the comparison shots they show look the same on both!
 
anyone else get the problem of it just being a white screen with sound?

I had that problem with the stream at first. A reinstall (repair actually) of Quicktime resolved it.

As for the podcast, it's WAY higher quality than the "High quality" stream. And it should be--it's 1.27GB!
