The error 224003 seen by Chrome users was a fault on my behalf. Some character speech was encoded as mono. All other effects in the video were stereo. Firefox and Safari had no problems but Chrome and Edge gave the unplayable video message. The problem has been corrected but I cannot update the video because the original is not deleted and keeps showing up. This is now a site problem which I cannot correct. So, the problem is one half mine (which I accept blame) and the other half is Renderosity's fault. :)
