 The following URL works fine with mplayer and VLC, but not ffplay:
 {{{
 http://direct.francetv.fr/regions/evt/medit-nice-direct.wsx?MSWMExt=.asf
 }}}
 However, using mmsh as protocol instead make it work:
 {{{
 mmsh://direct.francetv.fr/regions/evt/medit-nice-direct.wsx?MSWMExt=.asf
 }}}
 It looks like libavformat is missing some logic to recognize that a http
 URL is actually mms.

 The following is even "harder", as in that it doesn't work with mplayer or
 ffplay, and only VLC:
 {{{
 http://wm.microsoft.com/ms/evnet/Vista_Diagnostics_s_ch9.wmv
 }}}

 This is bad, because you can't just tell users they should try "mmsh"
 instead of "http" if "http" happens not to work.
