There are a bunch of casual match vids from Ikebukuro Las Vegas at madrigal's site:
"Movie" -> "SSF IIX" -> "Lasvegas Cup"
Volume 2 #s 15-40 were uploaded more recently. FWIW, the Grey Dictator/ST Sagat player (check out vol 2: 17-20, 23-28) is probably Taira.
The MSC DVD and MOF DVD sample movies are still up, too. Follow the links on the left sidebar.
