Query: 1 out of 3 ain't good.

I don't recommend this season of DVDs due to their malfunction. Discs 1 and 2 of season 4 are defective and cannot be played. Disc 3 appears to be playing fine so far. I played Seasons 1-3 (sold separately as a set) without a problem. I bought the 4th season separately. Season 4 is packaged differently and the on-screen menu looks different which may indicate a different manufacturer. Seasons 1-3 have the Paramount logo on the spine of the DVD case. Season 4 does not. I would suggest searching for a different manufacturer, if possible. I have not done that yet.
