How are you streaming video?  What commands are you launching at the 
client/server side?

I´m writing my own video client/server application, which calls mplayer as 
an external application.  I was  not able reproduce the problem you 
mentioned, because I have not a laptop/notebook available here, and I´m 
using a fast Internet connection.

I have a doubt regarding video streaming: how hard would be to use mplayer 
as a video player on an application such as GnomeMeeting (NetMeeting for 
Linux)?  Is it possible to use mplayer in a video conference application, 
over H.323?
