When Benedict XVI made the traditional Latin Mass (TLM) more readily available, EWTN broadcast them fairly frequently. There is a video archive on EWTN. As one can see, the most recent TLM archived is from 2009. Those are Masses offered in the church(es) of EWTN.
They also have those Masses on YouTube as well as Masses offered at other locations that were broadcast on EWTN. (Nota bene: the search results include Masses that are not TLMs - look for "traditional Latin Mass" or "Extraordinary form" in the title.)
