Earlier I created a custom downloader to download videos from //Build (2011) and was thinking about creating another one for //Build 2012.
I did however remember there was a batch download tool for Channel 9, where the //Build and other events are hosting their videos and searched for it and found it:
Select your //Build 2012 videos and download them here:
It creates either a PowerShell script or a WGET script for you to use and download the videos in one batch. Saves me some work to create another downloader.
The number of sessions this year was a lot lower than last year. Compared to last year //Build 2012 had only 60% of the number of sessions at //Build 2011 (275 last year against 164 this year). This is probably related to the fact that the venue in Anaheim in 2011 was much bigger and Microsoft Campus has only limited space to host their sessions.
Enjoy downloading and watching the //Build 2012 sessions!
