Hello, my name isXXXXX will do all I can to assist you in this.
Give it time, it may take a while.
When that finishes go to the Apple menu and select Software up dates, there are several for your Mac. This will bring it to 10.6.8 along with many updated drivers that you will need.
That camcorder uses AVCHD and mp4 format that iMovie will import directly without any additional software.
Apple - Support - Mac Apps - iMovie
I am assuming that you are not in the US because that camcorder uses PAL as opposed to NTSC, just a different way to play video.
It is listed as being supported in iMovie.
iMovie is now at 10.0.2 and will update automatically if it is now in your applications folder when you run software update.
If not then it is $15.00 in the App store.
Does that help? It may not be the final answer but it should be enough to get you started, let me know please.
