Source is local files or local DVDs. Destination is professional cinema beamer.
"Long distance" is the distance between the computer room and the projection room, ~10 meters, no more.
No point to use a streaming technology on LAN: the idea is to have a dedicated video server aside the beamer (but maybe not just aside because projection rooms are often crowded with argentic films related hardware.

I think it is important to have a card that is well supported from Linux (3D ?) so that it would be possible to deliver a 1600x1200 image at the rate of 25 frames a second without glitches during a whole film projection. This is for the New Ariston Cinema (Esch) that re-opens on the 22 june after having been completely refurbished, so the screen is ~25 meters diagonal. We don't speak about my livingroom here ! :-) 

I though N-Vidia would be ok. Are Matrox well supported ?

Thank you for your help.

I need to order a video-server PC (running on The OS),
    

Which kind? Does it need to be receiver for classic analog TV, DVB (-C, -T, -S)?
Or is it simply needed for streaming existing videos to some clients?

  
so I would like 
to have your advice concerning the best graphical card to play videos in 
High Definition and perfect quality on Linux.
    

Shouldn't about any graphics card be able to do so? Ok, depending on the
card, you'll get different signal qualities, especially high-res VGA can
be a problem. Therefore the question: which kind of device will be used
for visualization, CRT, TFT, Beamer, ...?
For good quality VGA signals, Matrox used to be a reference, from my
personal experience cheap NVidia-based cards won't do.

  
Aside from that, it should 
deliver the signal in S-Video or anything else that can be carried some 
tens of meters away.
    

... or stream via vlc or somesuch via network? Again, depends on the needs.
Long VGA cables exist, but must also be of good quality, so streaming via
network to another box can be a real alternative (remember Tux-Industries,
we used one "beamer-box" with several instances of X11, each one with a
VNC connection to one of the desktops, and switched around - saved a lot
on video hardware troubles).

Pierre may have some knowledge to share regarding vlc, some people at
the CRP have played with DVB etc., so if you can be more specific...

Greetings, Eric
