The Cantonese dub of the Sonic The Hedgehog OVA aired on TVB, it seems to have been shown only once sometime in 2000.
This dub is notable for editing out various scenes, cutting out scenes deemed unnecessary to accommodate for the channels more limited timeslot, or scenes that were deemed inappropriate for younger audiences.
Currently only the 2nd part of this dub is available, so its unknown how the 1st part was handled.
