I am not sure, but I think you would treat this as any other translated work. According to
this site MLA format would be this:
Cite as you would any other book. Add "Trans."—the abbreviation for
translated by—and follow with the name(s) of the translator(s).
Foucault, Michel. Madness and Civilization: A History of Insanity in
the Age of Reason. Trans. Richard Howard. New York: Vintage-Random
House, 1988. Print.
Combined that with the television show section:
Begin with the title of the episode in quotation marks. Provide the
name of the series or program in italics. Also include the network
name, call letters of the station followed by the city, and the date
of broadcast. End with the publication medium (e.g. Television,
Radio). For television episodes on Videocassette or DVD refer to the
“Recorded Television Episodes” section below.
"The Blessing Way." The X-Files. Fox. WXIA, Atlanta. 19 Jul. 1998.
and I would say the format would be:
"Episode Name." Show Title. Trans. Station or Channel. Station, City. Date of broadcast. Television.
