Cross Neuromancer with In the Mouth of Madness, add a little bit of Tron, Terminator, and set it in the Scooby-Doo universe and you pretty much have the basis for Cyber Chase.
The Mystery Inc. gang go visit a college friend who has made a video game based on their exploits. But instead of enjoying the novelty they are terrorized by an entity born of a computer virus who has entered the real world. The gang are beamed into their own video game (called Scooby-Doo and the Cyber Chase) and are forced to play through the levels in order to catch the virus (so to speak), eventually encountering their digital selves and digital versions of classic villains from the past. Sharp viewers will recognize Cyber-Shaggy's alternate costume from 13 Ghosts of Scooby Doo: Complete Series [DVD] [Region 1] [US Import] [NTSC
] and Scooby Doo and The Reluctant Werewolf [DVD
It's very clever, with loads of potential, most of which is not realized with the brisk run-time. At least you'll never get bored. It's certainly one of the most subversive and mind-bending Scooby adventures. A video game arcade featured towards the end of their titular Cyber Chase even features the Scooby-Doo and the Cyber Chase video game, thus making it self-referential meta-fiction within self-referential meta-fiction within self-referential fiction. Phew...get your head around that. And if that wasn't enough, it's the only Scooby-Doo animated feature to spawn its own real video game (for the PlayStation and Gameboy Advance), which would make that game self-referential fiction within...oh man, I'm getting dizzy.
Smart and tightly-written, Cyber Chase's lack of scope is the only thing preventing it from being a classic.
The Blu Ray looks great in 1.33:1 1080p, with colors so bright they literally pop off the screen. The sound is in DTS HD-MA, and there are a couple of minimal extras. Stay watching until the end of the credits for an extra scene.
