No, sorry, nothing.
Dear God in heaven, this is frustrating. Hours and hours and hours of troubleshooting, just endless.
IT WORKED TWO WEEKS AGO!
Went to Mac store to plug in my camera to one of their Macs - camera wasn't recognized.
Open the camera, all the videos are there. I just can't get to them.
Sony message boards have spider webs...no one answers.
Why in the heck can't I get my videos?
I even bypassed the Sony's USB cable and plugged in a firewire cable. Same thing.
The icons are on my desktop - one is called NO NAME and the other is PMBPORTABLE. Click them open, there are all sorts of things in there, and none are my videos.
I think maybe you have deleted some important files on your camera. Anyway, you can try to upload video to your Mac, then convert the mts file to imovie recognized format like mov. If you need you can see how to convert mts to mov on mac.
