Beta 7 for 1.01c firmware - changed PROPSET from 2 to 3.  This should fix a few things.

IXUS200-SD980 firmware 1.01C Beta 7

Still need more info on LCD XY resolution.

The LCD resolution doesn't matter; but the aspect ratio does.
It looks like it has a 16:9 LCD display - take a look at what Brend R did with the Ixus 1000 (I think).

I added some additional functions in lib.c for handling multiple image aspect ratios (see G12). There are defaults for these that you will probably need to override.

Also the viewport display width and buffer width may be different (again this can be handled in the new functions in lib.c).

It would help to see a photo of what the zebra/edge overlay actually looks like on the LCD.

Phil, I attach two images of what the grid overlay looks like (on BETA6).
Hope this will help. If you really need a picture of the edge overlay please let me know.

Thanks for that, yes a photo of the edge/zebra would help.

Grids are a different problem - they were designed for 4:3 LCD displays and the grid code isn't really set up to handle a 16:9 display. I think there were some work arounds done for the Ixus 1000; but there are fundamental problems that need to be solved. For example the 3:2 grid on a 4:3 display shows two lines, one near the top and one near the bottom - what should this grid look like on a 16:9 LCD? I think it should be two vertical lines; but there is no easy way to transform the grid file to do this in the code.

Yeah! Looks like over exposure issue is gone! This really rocks!
Thank you very much!

Yes, I confirm that shoot works fine, also in dng format.
Just one strange thing: when I try to turn on the camera in record mode, after the cdhk logo, it power off automatically while switching from play mode it works like a charm.

... and here are two pics of zebra which is actually not working correctly.
This is what happens when I half press shutter.

Well the zebra looks really weird but at least the edge overlay is recognizable so lets start there.
What does the edge overlay look like if the camera image size is set to 16:9 (again a photo would help)?

I own this camera, and I basically need CHDK for this camera to be worth anything to me.
So, I figured I'd finally try to assist after lurking this thread for so long.

The LCD display is said to be "230,000" pixels on various sites. It is 16:9.
Using this handy chart on wikipedia: http://en.wikipedia.org/wiki/List_of_common_resolutions

You can see that 230,000 pixels must be 640x360. Although in that chart the closest thing is 230,400 pixels. So maybe it's a few horizontal lines short of that.

If you need high resolution images of the camera doing anything in CHDK I'll try to get that for you.
