 I'll have a few friends help... Any of your corrupt pics good at the top? I have one that is good quality for about one tenth of the pic. That must mean theres something interrupting the write...  But for now, I just take two pics in continuous mode.

Looking at the code for the DNG files, I found that just after the line for the time stamp (line 14), if the whole pic is corrupt, at line 15 and on, the code is much different than good DNG  files. I don't think the problem is with the write process because I have a good time stamp along with other valid info.
 
 Anyone have any theories about whats going on?         ????

  It may be possible that the IS is causing the interference. Or the Auto focus. Has anyone tried turning these functions off then trying it out?

I have about every second shot working but seem over dark.

Photoshop CS4 recognizes the files now, before it just said corrupted.

No, neither IS nor auto focus, just 2 (or more) different raw buffer addresses, like on some other cameras...

Edit:...typos...

2 seams to fit the observation of every second picture getting corrupted.

some problems:

-need for video section :)
-random CHDK autodisabling (osd disappears), you can restore sometime with a swith-off, or sometime pushing randomly buttons, or see pictures in gallery and "play" with DISP button or others. sometime it's good too rotate the wheel :) amazing
-enable fast Ev switch appears on the screen, but if you change values with arrows, camera crash
-autobracketing in continuous mode crash sometimes quend you push shutter. with 10 shot settings, it takes 2, 3 or 4 pictures and then crash
-zebra doesn't work, histogram appears but doesn't work
-raw gives few good pictures with often "purple pictures"
- random crashes and restarting (sometime). when happens, camera buttons freeze, but for 10 seconds you can see image chengeing on screen


many others untested coming :)



this alpha version needs for a good adoptive father :)
btw thanks to all

   ...Yes, the magic of the broken wheel... Maybe the problem lies within the software recognizing the wheel...   I have setup the osd so that nothing conflicts with the original osd and everything seems to work! I halfpress the shutter release and it shows all the correct override values, then I take the picture. I'll upload it after work.

   It helps to run firmware from high speed cards...  My 2 gig high speed is used more than my regular 4 gig.

  I need to upgrade... Where I work, we run our firmware from CF cards. It really does help to have a faster card.
