Query: cheap=poor quality

Diamond Entertainment's DVD of 39 Steps is VHS (taped off a broadcast-TV late-late show in SLP mode) picture quality. Very soft. This is not what DVD is meant for. I can only comment on the Criterion Collection version for comparison. Criterion picture quality=9 out of 10, Diamond picture quality=3 out of 10 (10 being best). Save your money.
