I have a mess here!!!
I did all the steps : install VLC media player, install Knot2.
I am using win7 64bits
The VLC is installed in c:/program file(86)/videoLan/VLC
Knot 2 is isntalled in C:/program file(86)/knots
Then i start server in Start ->all program->knots->start server
Then enter configure server
It would open the browser with this link: http://localhost:1978/

Next i click on Collection button->choose the path that lead to my media folder on my Pc let say C:/Media collection->update collection-> Done it sees all the files in the Media collection.
Then i open knots on N900->open menu->transcoding profile there many profiles such as Nokia N900, local playback, browser, tablet browser....etc. However i chosse Nokia n900 and another is Browser->Connect automatically->Done it shows connected.

i do see folders and files on the pc from my phone.
I tried to play a song and it plays but no sound.
did i do anything wrong?
