In the case where there are multiple versions of the same movie, such as a 4K and a 2K version, if you use the Poster/v2/playVideo API call, passing the specific id of the version you wish to play, the Zidoo can ignore that choice and play a different version of the same movie title, one which has a different id. I first experienced this bug trying to play a new 4K copy of Harry Potter and the Sorcerer's Stone, but got the 2K version instead. A second time the Zidoo played the 2D version of Spider-Man: Homecoming instead of the 3D version I'd requested with its proper id. If I use the older ZidooPoster/PlayVideo API call, this bug does not occur. I recently updated my Zidoo to the v6.4.68_G firmware. This bug also did not occur with my previous firmware version, v6.4.62. This should narrow down where to search to find out when the bug was introduced.
