Yea, i know at some point they use glue in that DVD sandwich. On one of my Northern Exposure sets i had to return it because the glue had run out of the outer edge, and onto the playing surface. The outer rim was kind of lumpy and sticky. Since it came in a double Amery case i know it didn't come from the package. But i also notice they dont use that white inner ring like they did on older titles, like T2, or The Fog...i think. The only thing i know for FACT about the DVD-18s is they suck.
