A very exciting update on this topic. Almost every episode of Bob the Builder (1998-2011) is available on CBS All Access in their original aspect ratio. The only exception is Series 1, which is cropped to widescreen. Unfortunately, the shorts are not included, so the shorts will be excluded from my preservation. This may cost me money to preserve one episode from Series 5, as well as every episode from the following series, but I’ll hold out somehow.
