Here is another, more close-up, look at the second test that measures deinterlacing capability (480i/480p conversion). This test consists of three lines moving and down in rapid motion. In order to pass this test, at least one of the lines needs to be straight. If two lines are straight that would be considered better, and if three lines were straight, the results would be considered excellent.
As you can see, the lines are not jagged or wrinkled, and the bottom line shows just slight roughness along the edges.

This means that the Yamaha BD-S667 is passing this deinterlacing test.
