I´m afraid to use any patches, and version that arent stable since my camera made some ugly noise while using chdkptp. It sounded like some gears went crazy and skipped some tooths.
Can you be more specific about what you were doing when it happened, and what chdk build you were using?
I've never seen or heard of anything like that before. If it's a previously unknown problem, there's no reason to think "stable" builds will be any safer than any other build.
The only times I've had scary mechanical noises from the cameras are when they crashed with the lens part way out.
edit:
koshy is testing the live view changes, so there's no need for you to.
