I would like to report what was already known about battery's. Somehow the problem i had with fast wearing battery's was because of old and poor battery's that made me believe that chdk was using a lot more power.
Measuring with professional equipment only thing i can see is almost the same power usage with and without chdk (might be slight more as already reported with chdk but the difference is so small that i cannot really measure it or report that i really saw it).

Using Sanyo 2700mA had the same exact results with and without chdk
Using 3 different pairs of alkaline battery's had the exact same results with and without chdk
using 2 pairs of non alkaline battery's had the exact same results with and without chdk

conclusion leads to that the camera with chdk does use the same battery power that the camera without it uses.

I am really sorry for saying the opposite.

next step...

Auto Focus Scan during movie records works now. You have to (use the new
binary attached ...) configure an option "AF key" in OSD\video parameters.
This AF key triggers a AF scan while recording. It works for me. Because an
automatic AF scan is not available for SX110 you have to trigger it
manually. --> start your recording --> if cams has lost the focus then press
your AF key (I prefer <SET>) --> AF will readjust while movie is still
recording.

Solution: enable CAM_AF_SCAN_DURING_VIDEO_RECORD in camera.h and find
the address for some_flag_for_af_scan (stubs_min.S) in fw dump at
ROM:FFD19814.

New version of CHDK for SX110 attached!

and: dedicated to obihoernchen :-): Startup Sound works. Don't expect to much.
Solution: corrected wrong entry point of PT_PlaySound in stubs_entry_2.S "NHSTUB(PT_PlaySound, 0xFFC4D9AC)"

Cheers!

Would it be possible for someone to explain how to fix that? I seem not able to find --> configure an option "AF key" in OSD\video parameters. There is no such an option in Video parameters or i am looking in the wrong section of chdk (maybe i should alter a file in notepad?).
Maybe the build included 3 posts above by chdkj is newer than the latest CHDK Download autobuild?

Thanks in advance

Forget it i just found out that 3 posts above is different that CHDK Download page. Does work nicely.

Works fine for me. Nice Work! Maybe you're able to add the following feature:
While shooting a video, you press a button wich toggles the AF-assist-beam (or AF-Light -- the red LED in front) on and off. So that you can shoot videos in dark areas (with at least a little bit light)

I think "mute while focusing" option is very necessary. There are loud audio clicks when focusing. Possibly because red focusing light is used. Because there is 2 clicks when it goes on and when it goes off.

Several comments:

1) chdkj, the video zoom problem is definitely solved, I set the AF key in Main menu -> Video parameters, it works fine. Very good work! Thanks for sharing all this.

2) I don't think I am having a card performance problem. How come I can record the videos and playback them on the camera? Then I transfer them to the PC and can't play them anymore. A PC performance problem seems more likely. I ran new tests at 90% and now I can play the videos, but not every time. Sometimes, the playback gets jerky, it stutters or freezes for a second then it playbacks in fast motion for 2 or 3 seconds. My PC is an old 2200 Sempron, it must be it. The bitrate is so high my PC can't take it.

3) I don't see the point of applying mute while focusing. Between the camera's noise and interruptions of the audio, what's the difference? Which is worse? Audio is ruined anyway.

4) Has anyone managed to make any of the motion detection scripts work on the SX110IS?

maybe a new bug:
If I turn on the camera (holding on/off about 2 secs), the lens goes out, but sometimes the cam turns itself off (black screen, and nothing more), and the lens stays out. If I try to turn on-off again, the lens don't goes correctly back, just half way. It is just with the latest version.

The last update didn't work, the camera just shows a message that the card is locked.
I've installed back the previous version, and it works normally.

Are you using the file attached to the post (latest) or the one from the autobuild server? - The autobuild one doesn't work, the attached one(s) does.

If version from autobuild server has a lot of errors, could it be removed (until it becomes stable)?

Best guess is that the autobuild server is using the wrong keys for encrypting the image.
