Stream videos from Windows machine with "Media" using new beta?

HI folks.  I’m not sure how to stream movies from my Windows 7 machine using “Media” program.  This is all new to me as of a couple days ago so I’m not sure what to do.  THanks.

Figured it out…

Can you give me a brief of what you did?  I’m not getting access to my files.  

Me Too.  I have a Windows NAS drive, and using beta 5 still can’t find that thing.  Media - Add Share only allows a AFP share, that’s the apple sharing thing,right?  So where do the samba shares show up?  If I leave the media screen on “add share”, the only option is “Other”, and that gives me a spinning cursor that never goes anywhere, as if there are no shares on the network. The Nas is up and runing and visible from other computers during the search…

Figured it out - don`t forget to also install all of the updated applications that they have fixed at the same time - i.e. to get SMB sharing, update the media player etc etc…
