Today i bought a PS 1100IS and tried chdkptp and it is kinda messed up.
As youar camera an A1100, or ixus80_sd1100 ?
What CHDK and CHDKPTP versions are you using?
What OS are you using?
From the screenshots, it looks like the functions for full live view support are not implemented so the dimensions and palette are wrong. Looking at the code, this is true for A1100. The cut off live view looks like it might be due to digital zoom. This wouldn't happen if the viewport size functions were implemented.
It sounds like it went into rec mode but the display and function is like play mode. Is i press half shoot it goes into recmode but still with problems. The Screen ist mixed up as seen in the screenshoots attached. If i press half shoot the screen looks fine for a few seconds, but then goes back mixed up. I tried different usbports - no change. Everything works fine with the 590. Also functions go weird sometimes. I cant fully reproduce it, because it is so messed up. The graphics of the camera (not chdk) stay wrong, but chdk graphics look fine and the clock runs.
I don't really understand what you are trying to describe here. The screenshots show the display functions aren't fully implemented. The camera appears to be in rec mode.
I encountered a new issue where i put the camera in AEL to set the tv as i like. When i hit shootfull the camera doesnt respond to every button from Hardware and Software. If i hit a button in the software (chdkptp) it tells me a script is already running.
How are you trying to put the camera in AEL?
