I sent more than a dozen rolls to Dwaynes this fall. No scratches but a orange/green lines down the middel. I used 3 different cameras same results. The film was grainy. Again 3 cameras, indoor, outdoors with proper exposure. Dwaynes machine is designed for 35mm silde film not super 8. Kodachrome goes through a 14 step process in processing. The machine does not agitate the smaller guage properly so says Kodak.
