Ñahui : el rostro del Ecuador : serie audiovisual sobre los pueblos indígenas y negros del ecuador / Fundación ARIG ; dirección: Igor Guayasamin, Lilian Granda. (OCLC #919504054)

This 22 volume set has its container information (titles, summaries) all in Spanish, but for moving image materials we record the main language based on the sound track. This set includes videos in many languages (including Spanish, but also Awa pit, Kichwa, Paicoca, Cha’palaa, Huao terero, Shuar, A’ingae, and Tsafiki), so I encoded the soundtrack as having multiple languages:

Lang: mul

I encoded the information about container and subtitles in the 041:

with a free text version in the language note:
