This one just started today. During the next few weeks there should be more livestreams from Europe. Geneva, Olympia and Liverpool International normally livestream, and usually have excellent streams. There’s a British Dressage livestream December 3 too. We have most of those on the StreamHorseTV website already.
Here’s a direct link for the Longines Masters: http://www.longinesmasters.com/en/masters-tv
