Screwed by the Network: Screwed royally in Malaysia by government-owned TV 2. The show suffered lost scenes due to cutting to commercials without pausing the main tape and suffered an inconsistent schedule, but the worst thing was it was pre-empted halfway through season 1 for a whopping 6 months. TV 2 did not renew the license for Season 2, but the entirety of Season 2 did get a direct-to-DVD release in the country (Season 1 was also lucky enough to get a full DVD release in the country). Season 3 and 4 completely didn't make it in though.
