Well, a wild guess would be that Yamaha just thought that making this UI into the on screen display will be a lot of work and probably too complicated for most of the people who use it. Probably tweaking all this stuff from the remote will be more difficult than the web interface. So they try to keep things as simple as possible in the OSD. Actually, I am glad they still give all these options through the web interface. They could have removed them from the web as well
