Try this. These steps are for iMovie O9 but later versions should be similar.
Using the USB cable that came with the camera, and with the camera turned off, connect the camera to the computer.
Once connected turn the camera on.
On the computer LCD it should show a window with the message, "Please select USB Mode"
Select PC and press the OK/Menu button. In a few moments the camera will show up on the desktop as a drive called NO NAME
Start iMovie. Got to FILE IMPORT from Camera.
An import window should open and the movie clips on the camera should show. You can select the "movie clips" you want to import or just move the switch at the bottom from manual to auto to import all. Then click the button that says Import All, in the lower right corner.
You now have a choice to create a "New Event" or "Add to an Existing Event". If you are adding to another move chose Existing Event, if you are creating a new movie choose New Event. Give it a name or use the date provided.
Under Optimize Video make sure Full - Original Size is selected. Then Click import.
The new film should now show in the Event Library. Now you can create a new project (edited movie) and begin working.
DO NO Use VLC, Do NOT have Parallels running (sounds like VLC is running under Parallels not the native Mac OS) Turn off any other software that isn't needed. (Movies are memory intensive) If you have a fairly recent Mac it should run very smoothly.
Use the iMovie tutorials on apples website to learn how to use the software, though it is pretty intuitive once you get started.
Any other problems I will need to know your computer model, amount of RAM memory, processor type and if possible the graphics card or chip and if it is laptop or desktop because if it is choppy then it may be a hardware issue.
And I performed the exact steps above with my FZ150 using AVCHD movie quality in iTunes and it worked fine.
If you are using a card reader instead of connecting the camera directly, the only change is that instead of selecting "Import from Camera" you select "Import and then Movies" and point it towards the SD card in the card reader.
