Gotcha, I see now. You had me confused before, 'cuz I was gonna say that when you feed the wide models 1080i, you don't really need to use the aspect ratio controls (I actually posted a guide earlier in the thread that helps confused Mitsubishi users understand the various aspect ratio controls when displaying 4:3 content on a 16:9 set, as Mitsubishi's names for those settings could not possibly make less sense .

However, sometimes channels that play mostly HD sometimes have an hour long show - or maybe even 2 or 3 hours back to back - in SD, otherwise known in aspect ratio circles as 4x3. In those cases yes you'll be getting 1080i, but still with black side bars.
On my Dish 622 DVR, I am often changing the remote's Format AR control down at the lower left corner to expand/zoom because of this just to keep the screen filled up, even tho everything that comes out of my DVR is set to come out as 1080i.
