iDVD and iMovie won't import my .mpg's
I have a sony HDD handy cam (60gb). I just copied all the video from it to my computer and hit a wall. Nothing will open the files. The file extension is .mpg, but they won't open up in quicktime, nor are they recognized by iMovie, iDVD. Did I miss something? I've tried to retrieve the info through both programs, from the camera directly but no go.
I was pumped to get some DVD's burned today but was sorely disappointed.
Help?
