Query: Excellent series, flawed production

As an ardent fan of the series -- which originally was available to me only through video rentals -- I was excited at the prospect of owning my own copy. Unfortunately, surprisingly bad production values seem to plague the DVD release: 5 of the 6 discs on my copy had repeated tracking problems, resulting in frequent freeze-framing and occasional skipping. Although I'm willing to put up with this on a video rental, I think that the retail price is too high for such sloppy craftsmanship. And buyers beware: similar tracking problems also occurred with my copies of Seasons Two and Three. Until Showtime steps in and improves the quality of its DVDs, I would recommend acquiring it in VHS format -- or stopping by your nearest video rental!
