That's how I had to do mine as well. Maybe it's a Mac thing?Updated,... though it took me a few moments to figure out how to do it.
I had to copy the BIN file directly to the SD card while the card was inserted in my computer.
Inserted the SD card into the camera and followed the on screen instructions.
It looks like it downloaded correctly and I'll play with it tomorrow.
I'm hoping the new "Auto" mode corrects a problem I had last summer. At an out door concert I was playing in the picture was great until the sun went down. Then the picture got real grainy, even though there was plenty of lightning.I filmed a concert in the dark the other month and it was fine?
Not gonna bother yet.
