Seasons 1–4 were released on DVD in the U.S. by Rhino Entertainment Company/Kid Rhino Entertainment (under its "Rhinomation" classic animation entertainment brand) (a subsidiary of AOL Time Warner) (a division of Warner Music Group) between April 23, 2002, and March 9, 2004. Due to degradation of the original 1-inch master tapes, some sections of the Rhino Entertainment release use earlier incomplete animation, often introducing errors, such as mis-colored Decepticon jets, Skyfire colored like Skywarp, missing laser blasts, or a confusing sequence where Megatron, equipped with Skywarp's teleportation power, teleports but does not actually disappear. This version also added extra sound effects that were presented in the remixed 5.1 surround soundtrack, but not present in the original broadcast version.
