Hello,
I will buy a computer for mapping with pd + GEM and it would be nice to get some advice before I make a mistake.
I will be using 3 projectors so I though about using 2 nvidia cards to get 4 outputs (3 projectors + 1 screen for control), anyone knows if this is working easily with Linux? I want to get a Gemwin that covers the 3 screens.
I also want to get some video input from a camera or dvd or a VJ, I read on this list nice things about the Canopus ADVC-110 so I guess this is a good option but since I don't need it to be external maybe someone can recommend a nice internal card that works nice on Linux.
Thank you for the help.

yes that would work fine.
however i would recommend to get a matrox triplehead2go converter, so you need only a single (dual-headed) gfx card and you will still be able to run up to 6 screens with that.
personally i think that going through the hazzle of installing more than 1 gfx card is only worth it, if you need to run more than 6 screens.

generally all that uses dv as transport, will add quite a lot of latency to the video. best thing would be to use some analog grabber card i have good experience with brooktree/conexant bt8x8 chips (as found on hauppauge and other cards)

Thank you for the advice, I really appreciate it.
The reason I choose 2 cards instead of the triplehead2go was just to avoid hazzle, if the triplehead2go is easier to setup in Linux then I guess that is what I will use since I don't have much time and prefer to spend it creating nice visuals than setting up video cards.
For the capture card I was also worried about the latency so I will search for one with the bt8x8 chip, I don't know if it is easy because all the hauppauge I see for sale now are PCIe and say they have a new chip that I dont't know if it is working but I can always change it if doesn't work.
All good for you.

Look on eBay for "PCTV" PCI cards from Miro or from Hauppage or from Pinnacle, they are most likely bt8x8 based.

how the hell should i know? it mainly depends on your gfx-cards outputs and what your displays take as inputs.
i don't know why the device comes with a driver CD. i never loaded the CD, so i don't know what's on there. so don't let it frighten you.
the triplehead2go is really a very simplistic device: for the computer it is just a _monitor_ that sends rather unusual EDID information (e.g. it claims that it has a screen that is 3072x768 pixes large (and other resolutions)). you can then setup your gfx-card according to these specs (using xrandr, or the like (e.g. nvidia-settings))

While IOhannes is right about choosing triplehead2go according to your hardware, I confirm that I have successfully used the digital edition with both digital and analog hardware (on both ends with appropriate cabling, of course).
