It is actually quite intuitive...

There are direction arrows on the remote...

When you hit the "menu" button, it brought up the first option with a ">" next to it indicating that you could go into a sub menu, or you hit down for the next option. Left or right took you further into the options, or back out.

Or even direct access to the sound level of speakers would be great. Adjusting them durring the movie, not having to stop watching it first.
