Note that my raw capture was "upsampled" to make an anamorphic DVD, so what you see in that image has been vertically stretched from the original - this might have "masked" any jaggies that were present.
The DVDs that were on Suprnova were Dr Gonzo's, however, it is unclear whether they were identical to his originals that were posted to Usenet or if they had been tampered with in any way before torrenting.
