How difficult would it be to lable two-sided discs with something so simple as "side A" or "side B"? For example on the current "Dr Zhivago" disc the only difference between the A and B sides is that the catalog number ends with an A or B in small type. The same is true on "Ben Hur" and "Superman". Now "The Wild Bunch" from the dark ages of DVD is clearly marked with side info. Surely the ink doesn't cost that much.
