How do I download the videos?
- To download, right click the file type you would like and pick “Save target as…” or “Save link as…”
Why should I download videos from Channel9?
- It's an easy way to save the videos you like locally.
- You can save the videos in order to watch them offline.
- If all you want is to hear the audio, you can download the MP3!
Which version should I choose?
- If you want to view the video on your PC, Xbox or Media Center, download the High Quality WMV file (this is the highest quality version we have available).
- If you'd like a lower bitrate version, to reduce the download time or cost, then choose the Medium Quality WMV file.
- If you have a Zune, WP7, iPhone, iPad, or iPod device, choose the low or medium MP4 file.
- If you just want to hear the audio of the video, choose the MP3 file.
Right click “Save as…”
- Mid Quality WMV (Lo-band, Mobile)
In Part I of this two part screencast, Microsoft Federal Developer Evangelist Marc Schweigert demonstrates the basic concepts used build a mashup application using the Virtual Earth map control and AJAX style programming. In
Part II, we’ll build the same solution using ASP.NET “Atlas.”
This screencast was inspired by various tutorials and walkthroughs from the following:

Question:
"I've already worked on this kind of development, and i'm impressed with Visual Studio JavaScript debugging facilities...
Is it standard with Visual Studio 2005?"
Answer:
"Yes. It's a little known feature of Visual Studio / IE. It is not enabled by default. Just go to Tools->Internet Options (in IE). Then go to the Advanced tab. Make sure both "Disable Script Debugging" checkboxes are unchecked. Now set a breakpoint in your JavaScript. You should now have JavaScript debugging enabled. It definitely makes JavaScript programming a little more productive

Small (but important) typo in the code though:
xmlhttp.Open("GET", url, true);
should be
xmlhttp.open("GET", url, true);
or else it won't work in the fox.
Thanks again.
If you have a moment I'm working on the logic to introduce clustering of points server side based on your AJAX code.

Thanks!!
Can u help?
I have an open source Virtual Earth mapping control using ASP.NET AJAX Extensions that I've been working on for awhile now. It's hosted over at CodePlex, so check it out if you're interested.
