Hallo Austin/ Mike
thanks for the recommendations.
What I found so far is a multple moitor card for
laptops (still talking MAC) called VTBook.
This seems to support upto 3 external monitors on
a powerbook. And it also seems to be okay in

What I did not find is a player that would
support presentation mode on multiple screens. On
a search I steped on MPlayer, but I could not
figure out if that would do the job, it was not
clear from the descritption, and it is rather
difficult to install. As far as I understand, you
need to download components and to build MPlayer
yourself (I will try it, but it needs some more
reading on my side on how to use the terminal, it
is a long time I used it). Does anybody know if
MPlayer does multple full screen presentations?
Is there any other MAC player that does it?

At the moment it looks like this would be the
most fisible possibility, the Dave Jones Design
is out of question as it works only with the
professional Pioneer DVD player Dvd Pioneer
V7300d in Europe, which is outrages in price. And
I do not have a programmer who would configure
MAX/msp for me.

Thank you very much for the help.
