It's not streaming, it's simply playing the file over SMB networking, which uses ports 137-139.

so it does not use port 445?

also, i did a trace with Etherreal and it appears it use both 445(SMB port) and 36631(where the video data is coming from)

it like this:
SMB - next packat length
SMB - Ack
TCP(36631) data
TCP(36631) Confirm
--------Repeat pattern---------

what i really want to know is when i watch a video from a Pocket PC does it also use port 445 and 36631?

If you're just reading it off a standard network drive it's just reading the data through SMB.  If you are using another protocol, things might be different.

its will be the Betaplayer (now know as TCPMP player), watching a avi file
137,139,445 via SMB/NetBIOS.  

If your streaming video then the port depends on the streaming server application. How is the pocket PC connected to the server?

sakuya_suAuthor Commented:
What player are you using on the Pocket PC? And what path/URL aer you using to connect the the stream?

sakuya_suAuthor Commented:
betaplayer, path is \\server\d\movie.avi
Then it's only using 137,139 and 445.
