Having a problem embedding YouTube video's in my web site, some work OK others will not. The ID seems to be the issue.
If the ID format is xxxxxxxx an example is yQU9e-ZKRTw it plays OK. If the ID is formatted as xxxxxxx=xx an example BQoPfGCvnXs&t=9s
it will not play, just get a black screen and an error message. In both examples allow embedding is ticked on in the advanced properties. Any ideas?
