As always, thanks for the help!
The DVD´s i´m looking at are "generic" dvds of promotional videos from a client. there is no other information on the disks other than the 5 video chapters, no menus, no nothing.
Its the ones I had a few weeks ago in the north of spain. There I was using the video capture card and playing them via a standard DVD player.. however the quality of the image, when playing them direct from the pc´s drive, is astonishing!
We´re currently testing SM in line with a 7.5x2.5 mtr screen in the warehouse....
