Query: dissapointment

The dvds arrived on time. The package was opened and the DVDs do not read in the Canon DC50 camcorder it was bought for. From what I am seeing in the one staer reviews is these DVDs are not compatible with some camcorders. Sony DVDs of the same type worked fine. The funny part is if they were opened they were probably returned by someone else. Why send them to me? This is very unusual. I am usually happy with my amazon purchases. It gets one star for arriving in a timely manner, and hopefully for their return policy.
