Did you compile the grabber by making Allegro? Did you make it >for DJGPP or maybe MSVC? I think the problem is a cheap video card, I have the same situation when I run the grabber. I have a Tamarack VGA with PVGA1A chipset (i've never heard of it either :) and for some reason all programs think it can do 640x480x256 when in fact it can only do up to 640x400. Unfortunately even 640x400 it is unusable with a lot of streaking everytime the screen get drawn. So since Allegro only supports 256+ colors I must run grabber with 'grabber -320x240' ... The same problem is evident when I run some of the example programs. > >Also, you can try running the grabber in a different depth and resolution. >Maybe another color depth/resolution will work. > > >>By default, the grabber will run in a 640x480 resolution, using the highest >>color depth possible on your graphics card.
