Frankly, I need more help here - at least 3 people have been downloading these beta releases but only voodoolady has been helping out by providing feedback.

Sorry waterwingz, my computer has been down for a while. I will download the Beta 10 and see what i can find from there. Im having a small problem trying to format and make the card bootable as i have a 16GB card... I guess ill have to make a 4 GB partition or load it manually to test.
I have heard about the multi partition on  CHDK, but has that been implemented already? If so i can check on that too.

Anyways, i will report back again. Thank you waterwingz for all the effort and helping us with 1.00B

Take a look here :  http://chdk.wikia.com/wiki/Bootable_SD_card.  Follow the instructions for sdminste.exe.  http://stereo.jpn.org/eng/sdm/quick.htm

Thank you for the links waterwingz.

I followed the instructions and got the dual partition working on my 16 GB card. :D
It seems to load properly

I didnt have much time to really understand how to use CHDK, but i noticed one thing...
When I do half-press and focus on the object, default OSD information disappears and doesnt come back until I go into the menu or something. It seems to lose the default camera informations and not the ones displayed by the CHDK (eg. # of shots left, mode, resolution, flash, etc.). Is this normal?

Ill keep testing and report back.

Screen refresh for CHDK OSD and menu information is a problem with CHDK on many cameras in shooting mode.   Recently, philmoz has improved this a bit for some cameras but it has not been implemented  on all cameras.  So for now,  what you are seeing is normal for the SD780.

Thank you for the clarification waterwingz.
Im sorry if I keep posting some problems that are already known to CHDK.
Ill keep reading up on CHDK and hopefully I will stop doing that soon.
Anyways, I was testing the video mode a little bit and found something.

When I set the Video Mode = Quality and then made the Video Quality = "99" under Video Parameters,
a red "!" shows up and the video recording stops after 1 sec. Even if I lower the Video quality (e.g. 80), same thing happens.
This may be just due to my memory card as I am using Sandisk Class 2, however I tested this card to have stable write speed at ~6.6 MB/s and read speed ~ 18.2 MB/s using H2testw v1.4.
I am wondering if someone else can test this (possibly on a higher class card) and check the video recording is working in Quality mode.

Hi. I just wanted to mention that on the 1.00C CHDK build for the SD780 IS increasing the video quality mode just seems to increase the data rate without any noticeable visual improvement in video image quality. It might be a similar issue on the FW1.00B CHDK version too.

a red "!" shows up and the video recording stops after 1 sec. Even if I lower the Video quality (e.g. 80), same thing happens.

Don't feel you have to apologize - there is no way for anyone to know every quirk of CHDK. When I suggested that a problem is well known,  I'm only pointing out that is not an issue with the specific port so not something easily fixed (at least by me).

Having said that,  it now appears that the disappearing menu problem can be easily solved - I'll post an update shortly.

You are on the right path I think.   Even though your memory card might seem fast enough,  experience says it needs to be quite a bit faster to allow the camera processor some time to work on the video.  It seems the camera wants to write in very fast bursts rather than a slower continuous rate that the card could handle.   Or at least that's my best theory.

For a class 2 card,  I've seen reports of max usable quaility levels  around 70.  And your little camera might even be slower.  Does it work at 50 or 60 - just to make sure the code runs ?

UPDATES for the IXUS100-SD780

Here's a couple of links for the two new releases for the IXUS100-SD780.   Both versions should now have the "dissappearing menu when shooting" problem fixed.

I also updated the 1.00c to match the newer 1.00b.  

IXUS100-SD780 firmware 1.00B]http://www.box.net/shared/n0564jl6y3o6o6v5qca5] IXUS100-SD780 firmware 1.00B
IXUS100-SD780 firmware 1.00C]http://www.box.net/shared/on0x5qi1xf9uf885muql] IXUS100-SD780 firmware 1.00C

If I get feedback that both of these versions work properly, I'll submit to the autobuild server.

UPDATE 2: now available from the autobuild server

UPDATE :  I've attached a patch file suitable for submission for inclusion in the trunk.  Worth having in case I don't get back here and somebody wants to pick this up down the road.  Or if we get some testing information for the 1.00B & 1.00C suggesting this update works as promised.

I just tested the 1.00B version, Canon and CHDK OSD remains on the screen.

I also checked the video parameters as you suggested. I took the video in QUALITY mode set at 50 and 60, it seems to be working fine. I changed the quality to 70 and the camera showed a red "!" so maybe you are right that my card/camera is too slow for recording at higher quality. Ill  get a class 10 card and test later.

again, thank you for spending the time to help us with 1.00B firmware.

It would be good to hear that the 1.00C version works too.  Then I can submit the patch file for inclusion in the autobuild.

IXUS100-SD780 firmware 1.00C

UPDATE :  Link deleted - now in autobuild server.
