Several netstream plugin or several dvbviewers

[optica11]

I would like to have several netstream plugin working simultaneusly, I've try it runing two dvbviewers and it works (one DVBViewer with one tv card), but when I try 3 dvbviewers simultaneusly, the third doesn't work. I don't want watch tv in my "server", I only want one netstream plugin for one transponder. I think I need 6 dvbviewers with netstream plugin working in different ports and 6 tv cards, because I have 6 transponders.

I execute several dvbviewers making a copy of DVBViewer folders for every instance, and changing the root in usermode.ini, but only two instances works. Are there anyother posibility for runing several dvbviewers???

Could I disable the sound and the image in the dvbviewers and work only with netstream plugin??

I've already study dvbserver, and now I would like to know this.
