YESSSSS !!
Zooms in by steps of 12 - perfect. Zooms out perfectly too.
Now I have a clear mind and can finish building the rig.
Seriously, I have both Mac and PC experience (lots!), but I didn't know that unzipping to the card itself would make a difference. I appreciate your efforts! I'm curious - is this patch just for me and the other megazoom cameras, or will become part of the next release?
This has been a terrific experience...I spent a lot of time going over the design of my controller, thinking it was the problem. But it wasn't. I use a 9v battery (out of convenience) and a simple voltage divider to get the 4.5v USB trigger.
Thank you for coming to the rescue!
Just saw your last reply.......the first time, I replaced ONLY the CHDK folder on the card with the new unzipped one. I never changed any root-level files on the card.
Don't worry, It's looking good now.
