Rev 4 Preview Webinar - Video Link

[Richmond Mathewson]

I think one can get a bit too hoity-toity about commercial software; and 
I am not fan number 1 of Microsoft either;
BUT, as VLC (which is Open Source, Hurrah, Hurrah, Hurrah) plays WMV 
files "just like that" we should not complain.

I know, Andre, that if somebody suggested I ran out and bought 2 dv 
cameras and then spent ages fiddling around reimporting
the recorded video files and so on I would get a bit miffed.

Obviously the chaps on the Webinar did "what came naturally" with the 
broadcast software; I know I would.
