Query: Had to be returned since Seasons 1-3 were defective

I eagerly purchased both sets of Seasons 1-3 along with Season 4. Seasons 1-3 were extremely glitchy and un-watchable. I returned both DVD sets back to Amazon since season 4 would be useless without seasons 1-3.I have found in the past that usually if a series is glitchy and you get a second one to replace it right away, the next set is usually also glitchy. I think it has to do with the fact that so many discs are produced at one time that they would all be defective from that production run.
