I have an HD Sony Handycam and recorded home videos on to a 32 GB San Disk Ultra. I uploaded the footage to my updated Mac via card reader and I see all the .mov files where i archived them. when I click on one clip in quicktime I see movie and sound for about 5 sec and it stops as if it were a huge file. iMovie and iDVD take forever with it. What the heck? I want to be able to store and keep these memories in an organized manner and be able to burn them to DVD and share with the rest of the family. One clip is 267MB. Please help..
