I can´t stream video

I just installed opensuse 11.2 on my laptop. I have one problem that i didn´t have in the earlier versions.

I have another computer, running Windows 7. On that computer I have a lot of videos i a shared folder. So when i boot Windows 7 on my other computer I can stream them over the network. But when i instead boot opensuse 11.2 it won´t work. If I use KmPlayer, it first says buffering and then just says ready and wont play. If i use sm player for example it tries to copy the file first, but I just want to stream it. It worked on 10.3, 11.0 and so on.

Someone who knows how i can fix it?

ps. I can stream if I use XBMC, but i dont want to start XBMC for every little video I want to play.
