I get an error message when I tried to play the video:

Media Failure. Try reloading the page or visiting the main site for assistance.

I tried reloading the page without success.

Hi Tavis, try playing the video now. Usually it is not the video but the site. When you see that message come back to the video later and it tends to be fixed. It worked for me now. Let me know!

Thanks for posting this presentation.

Bad news: Sound for this slideshow won't play in Silverlight 3.0.50106.0 (from silverlight.net) in IE 8.0.6001.1870 and FF 3.6, Win XP SP3 + all updates, AMD Sempron 1.8GHz. I don't think it's a CPU issue, because other videos do play with sound, such as this one uploaded by Jossie on the same day (Sept. 23, 2009): http://channel9.msdn.com/posts/Jossie/Connected-Information-Security-Framework-Core-Components/ and http://channel9.msdn.com/posts/Jossie/Technical-Preview-for-CATNET-20/

Good news, workaround: copying the URL from the embed HTML ( < /> icon) and pasting it into Windows Media Player 11 "Open URL", the video+audio streams perfectly:

http://ecn.channel9.msdn.com/o9/ch9/6/9/6/3/9/4/antiXSS31_ch9.wmv

The trouble?: WMP11 says the audio codec is: "Windows Media Audio 10 Professional, 128 kbps, 44 kHz, 2 channel 24 bit 2-pass VBR". 24 bits seems like overkill for a voiceover, and Silverlight 3.0 won't play it. (Or is it a container problem?)

Suggestion: In future, encode audio for WMA 9 and/or 16 bit for maximum backward compatibility.

Can I use this on classic ASP applications? Please point me to a right article or video if we can?

Thanks,

Unfortunately both Anti-XSS library and CAT.NET work on mangaed code. It can't be used with classic ASP applications.
