I still have Black Bars on some of my DVD's. I know some are suppose to be there when there 2.35:1 but some times they are there when there not suposed to be.
The problems:
The Three Musketeers 2.35:1 has the black bars the size of letterbox like if you made a 4:3 letterbox movie (like on the Sci-Fi Channel every once in a while) to 16:9. I had to set my TV to Expand to make the picture look right but every once and a while you could see aliasing this way.
Chronicles of Riddick: Dark Fury and Van Helsing: London Assignment are both 16:9 widescreen but they have black bars.

Those are the only ones that I know don't work correctly. I have watched close to 30 DVD's in the past month and a half, they are all rented from Blockbuster and are all the Widescreen Editions. The Three Musketeers is the last one I watched but I watched many movies between the the other two that didn't work right.
All the settings on the DVD player are correct, Proggressive through component cables to Mitsubishi WD-52525 DLP, DVD player is Samsung DVD/VCR combo DVD-V4600.

I also posted this in the FAQ section but it could take months for a response so I thought I would make a new thread.

You must have your DVD player in 4:3 instead of 16:9 mode. Or you have some strange combination of zoom and stretch.

Some of movies that are widescreen 16X9 have black bars if it is enhanced 16x9 you can zoom the picture to fill the screen. widescreen 1:85:1 films will fill the screen without bars.
what you are seeing is normal
