Thanks to Michel de Rooij on TechNet gallery for posting this slick script where you can download TechNet content locally to your machine.

I wanted to select which videos to download, and wrote this powershell script to use out-gridview to download content. It calls the script above.
Usage:
You can run the command directly from powershell, just cut and paste this command:

Comments:
- Will download and cache the content locally so you can re-run the script repeatedly without having to wait to parse the website.
- Will then display all the sessions in the PowerShell Out-GridView. Out-gridview is powerful.
- Then will ask If you want to save the list to a *.html file for online viewing later.
- Will also ask if you want to save the offline content to a local file.
