I am trying to get a hand on a point grey to run tests.... I found this page that lists uncompressed firewire cameras: http://damien.douxchamps.net/ieee1394/cameras/index.php This one seems to have the best pfs for the price (199$), it's called firefly MV, however I will continue the search: http://www.ptgrey.com/products/fireflymv/index.asp http://www.ptgrey.com/products/fireflymv/fireflymv.pdf http://www.ptgrey.com/products/Point_Grey_imaging_catalog.pdf good luck and if you get good fps for good price with uncompressed firewire let me know... best, J On 11/15/07, Olivier Heinry <[EMAIL PROTECTED]> wrote: > Le jeudi 15 novembre 2007 à 20:23 -0800, Jaime Oliver a écrit : > > I think your problem may not be in the driver but in the fact that you > > are using DV which compresses both at the camera and in your computer > > bus...
