It's likely that your projector ever so slightly overscans. The black bars on 1.85 material are rather negligable on a 1.78 display. Try using a HTPC to get 1:1 mapping. You should see slight bars then.
|All projectors should come with zero overscan, and give you the option of using it if you so desire. Anything less is ridiculous to me. It would be so easy to do, yet I know of no manufacturer who has accomplished it.|

5% overscan is normal for a television and is nothing to be concerned with. This is usually enough to make the black bars on 1.85:1 movies disappear on a 16:9 screen. A projector doesn't have the physical need for overscan like tube TVs do, but some manufacturers build it in anyway for consistency. Also, if you try watching broadcast television on a display calibrated for zero overscan you'll see all sorts of distracting signal crap along the edges of the picture that you're not meant to see.
As Vlad points out, most video calibration discs (like Avia, or Digital Video Essentials) have test patterns for determining how much overscan your display has. Like I said, anything 5% or less is nothing to be concerned about.
