--- Comment #1 from Santino Mazza smazza@codeweavers.com --- I think this is related to a problem I found in Close Combat 3 after implementing dynamic formats in the ddraw stream, where the video plays with the wrong pixel format. This is probably related to quartz parser not checking for media type changes on the samples it obtains from the mem allocator. Also, I think we might have to change set the properties of the memory allocator to change the sample size to the new format.
I'm going to be working on this.
