[SOLVED] Mkv work in usb but not by lan

[atomico]

Hello, i have xbian on a raspberry pi but today i have a big problem.. i have some mkv file on my pc windows that i share on the network by shared folder of windows (samba).

from xbian i added the source and so i can see all files. i have about 40mkv files, 30 of these work perfeclty while some don't work (i click on the name but nothing happen.. no waiting message and nothing)

i tried the same files over a usb harddrive and work as a charm.

so what is the problem?

thanks
