No, dropping the DVDs product line will decrease operating income by $31,000, resulting in a total loss of $40,000. Even though the DVDs product line by itself is not profitable, it absorbs a large percentage of the fixed costs and if you get rid of it, all the fixed costs will be absorbed by the Blue-rays product line.
