I still couldn't record at 98%, but it *seems* to have recorded at 97%. Large files are recorded (20 secs. = 105 Mb), but I can't playback them entirely on my Linux box. Mplayer just playbacks two or three seconds and closes. Sometimes it will play a few more seconds, but never all the way through. They playback correctly on the camera.

No, you got that backwards. I can play it fine on the camera, I can't play it on the PC. EDIT: I mean, I copy the file to the HD before playing it on the PC.
I can watch entirely such recorded files (>300 MB) with mplayer and
kaffeine on my linux box. Something wrong with your config (codecs..)?

I just tested the new release. Optical zoom now works in video mode, but I do lose focus after 70% or so.

Also, I changed the recording mode from Bitrate to Quality and the camera kind of crashed when I tried to record video. The screen turned off immediately and the controls would not respond, except the power button, it does turn the camera off. I could turn back on again, no need to remove batteries. Nothing was recorded. I tried three times, same result every time.

In Quality mode I think camera can't record to SD fast enough. Thats why I think it crushes. If you lower the quality to 98% camera will not crush! Also if video gets busy @ 98% it will crush as well.720is chdk had some kind protection against that. If your SD isn't fast enough for recording it just stops the recording. If you're right on the edge then warning sing flashes on the screen. Also with 720is I found out the difference between different SD card speeds. Generic cards will stop at around 50%. Better cards will go up to 84%. Excellent cards can go to 98% I have one SanDisk 1GB that can do 99%.

When you zoom 100% without recording, camera can focus no problem. But when you recording and zooming >70% then there is a problem. I think it's a bug.
I'm using a SanDisk SDHC 4GB Ultra II --> recorded movies with Quality @99%.
"dd" wrote  to this card with 18.0 MB/s.
I'm pretty sure is a matter of card performance (like Inferno said).

sure.. i'll explain.
Auto-ISO-Shift ist not the normal Auto-ISO. Auto-Iso-Shift works like this:

Rec-Mode -> menu -> activate auto-iso-shift.
go to P- TV- AV- or M-Mode -> change iso (for example) to 80 (should be a low number).
Go somewhere, where the light is not so bright (some kind of "darkish" area).
half-press the shot-button. Now the Print-Button should be blue. press the print-Button.
Now you should see how the ISO and the exposure-time changed to recommended (AUTO) settings.


greetings

Aaahh, I see. Now I understand. Was not aware of this feature. Going to check this.. Thanks for your explanation.

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!

EDIT: Attachment deleted (final version released on Autobuild already)

Thanks a lot chdkj
autofocus is now working :)

by the way.. instead of SET button.. can i use the Zoom button straightway?

like when i press zoom, it will zoom and auto focus both at the same time?
can zoom button be added in AF key[    ]?

Thanks a lot!
