Opacity is the translucence of an object. In other words an option to make the HUD slightly see-through, not just move it.

Oh, you mean this thing (english isn't my native language). Sure, why not. They could include this, but after they haven't include MANY other basic features I doubt they will. If you have problem with burned in HUD, then at least you can move it a little every hour (or so). However, if you still have warranty for you TV, I'd say it's time to use it. No modern plasmas should have this kind of issue. My father bought 50" Panasonic something around 5 years ago. TV is on for most of time (even my nephew is playing Halo on this TV) and there was no such problems. No burned in channel's logos, no game's HUDs, nothing like that.
