Is generally more information from the source not better than less?
There is no more information. The source (DVD/Blu-ray) is subsampled in 4:2:0. When outputting YUY2 the decoder itself does the upsampling to 4:2:2 which is usually much worse than the upsampling madVR does. YV12 ensures that the decoder outputs the data as decoded. This is the reason why YV12 is better in this case.
