Well this isn't a good searching strategy. You know how gnutella works? Many users are sharing files with a "divx" substring. So there are two scenarios:[list=1][*] every user sharing "divx" is replying you request, then the network is swamped with these replys and the network is going down.[*] newer clients only send a few replies per request to save the network, so maybe the movie you are looking for is hidden.[/list=1]
So you should seach with terms like "movie of my choice" and then set a filter string of "divx" for best results. If you like to look, what's around in the network, you should try passive seach, you can sort the columns by filesize so best results are on top.
