Custom resolution won't save?

I'm trying to set the resolution in Windows to my projector's native 854x480, but it reverts to 848x480 upon rebooting. I've tried both editing the registry and using PowerStrip.

4.5.1 Why is it important to have the height and width of the raster image divisible by 16?
Modern digital video applications such as DV, DVD and digital television (DVB, ATSC) often use MPEG-1 or MPEG-2 formats (or their derivatives) which are all based on 16×16 pixel macroblocks. Having the height and width of the image readily divisible by 16 makes it easier and more efficient for an MPEG encoder to compress video.

On the other hand, there are pleny of resolutions that aren't divisible by 16, 800x600, 1400x1050, 1800x1440, 1920x1080.

So, is this normal? Is there a way around it?

Thanks.

PS: The reason that it is important is because 848x480 is 1.77:1 (not 16:9), and 854x480 is 1.78:1 - HDTV 16:9.
