I was excited to see that this item was going to be released at long last. I had purchased all the individual seasons as soon as each became available, but seasons 6 & 7 were never released on DVD until this set became available. Now that I have this item in-hand, I must say I'm very disappointed. Many people in various reviews have already mentioned how weak and susceptible to damage the packing is, but what I was not prepared for was how awful the video quality would be for the final two seasons.
Seasons 1-5 appear to be the same transfers as the previous releases, which is a good thing, but seasons 6 & 7 were mastered with an incorrectly blended frame rate at 29.97 fps. While previous releases were encoded at 29.97-interlaced, which could be detelecine'd back to 23.98 fps easily without noticeable quality degradation, more than half of the episodes in seasons 6 & 7 were mastered with noticeable frame blending as well as interlacing, making it impossible to view the images with clarity, even after going through a detelecine process. As a viewer with an eye for quality, I find this completely unacceptable, and I'm frankly surprised that Mill Creek allowed this to pass even the most relaxed of quality assurance inspections (assuming they have such a thing, which it's beginning to seem they may not).
Due to the poor video quality and the cheap packaging, I am forced to give this set a fairly low rating. The 2 stars earned are strictly for seasons 1-5, which were already available, and not produced by Mill Creek.
