OK, I'll try it.
I was using SimplyMepis...just playin' around before I had to do (another) Windows install.
That White Sox video plays for me too, but when I try to connect to a stream....nothing.
Hmmmm...
Mlb.com is exclusively Windows Media now, so you'll have to cobble together some sort of hack or emulation to get Linux to work.
Detecting OS...
In order to offer a broad selection of full-length music
videos on-demand and free of charge, MTV Overdrive uses
Windows Digital Rights Management (DRM) to protect videos
from unauthorized re-distribution.
Unfortunately, Microsoft's Windows Media Player Plug-in for
Unix does not support Windows DRM. If DRM support becomes
available, MTV will develop a version of MTV Overdrive
that works for your operating system.
Good 'ol DRM....
