Questions about realplayer

[Derek <spam37512@gmail.com>]

Hello,I am trying to play the video highlights from nba.com but
realplayer and helix player will not play them.It says "The following
components are required video/x-ms-asf".I am using realplayer
10.0.5.756.Is there any way I can play this stuff?Also,what is the
difference between helix player and real player?Do I even need real
player?
Thank you,
Derek
