Keep Circulating the Tapes: Unlike Nickelodeon, Disney has never released a full boxset DVD collection of any of its DCLAU series, including its most popular and seminal series like Hannah Montana, The Suite Life of Zack and Cody and Lizzie McGuire (However, there are boxsets for these shows but only outside North America). Some recently completed series that still get big draws like Suite Life on Deck and Wizards of Waverly Place will be shown during the Graveyard Hours (and not the full run either - for example, any episodes that run past the standard 23-minute run time - including the extended finales - will simply be left out of the run altogether). DVD collections do exist, but they're typically just a handful of random episodes, about three to five tops to represent an entire 65 to 80 (or more) episode series. Other than that, just about the only way to see any older series is through YouTube or file sharing sites.
The older DCOMs (except for the mega-popular ones that practically define the network, such as High School Musical) might be shown during the Graveyard Hours even beyond what's mentioned above. Somewhat annoying considering that they tend to play newer DCOMs nearly to death during primetime hours.
Disney Channel's "Throwback Thursday" block (actually closer to "Throwback Wednesday" since it airs right at Midnight) has helped get some of the older series and DCOMs some exposure, two episodes or a single DCOM a week at a time.
Some of the series are available in their entirety on Netflix, however.
Most of the shows in the DCLAU are produced by It's a Laugh Productions.
