Laserschwert, I'll presume you don't have usenet access or haven't seen the covers Wookie Groomer posted.
That's a lo-rez version of his A New Hope cover which shows two screenshots.
According to my own extrapolations, each film frame would be approximately 1200x510.
Obviously GOUT is upscaled, but WG didn't divulge in his .NFO file which method he used to resize.
