Based on this thread:
Now I still can't be able to download PDC 2010 slides! I'm very sorry I have to "reopen" this.
Please, pleeaasseee fix this.
FYI: I can't download on microsoftpdc.com site, and it'll always redirect to this channel9. I find it very strange when I can download PDC 2009 slides, but I can't download PDC 2010 slides.
