madaboutvideo

Hi, I am using Watchout 6, and am loading an Apple prores 422 File, and it is playing ok, however when starting an error comes in the Messages window saying: Unable to render DS video. Everything continues to play normally. One thing I noticed, after dragging the media on the timeline is that with prores media only, there is some sort of an extension in front of it. Can anyone give an answer to what is happening? Regards,
