Has anyone noticed, when watching seasons 1-4, that the quality of the image and audio are not bad (almost as if they were restored, somewhat) versus seasons 5-7, the print quality/sound is awful. It's almost as if they're 4th or 5th generation copies. The print quality is better the rest of the series. Just something that bothered me when watching reruns. It's especially more noticeable nowadays with HD sets.
