Hey, I could use some help. My camera (Pentax Optio A20) can take videos, and says says on the camera that they are Divx and Mpeg-4 files. However, when I connect it to my mac, the videos appear as avi files. When I try to play them in quicktime, there is no audio. when i first tried to open the movies in iphoto (they got imported with my other movies) it said that i was missing components to play the video correctly and took me to a site. i tried to download and load various codecs, but it still refuses to work. however, when i open the files with vlc player, the audio works. this is no help though because i need to edit the files in imovie, and it will not let me select them. any advice?
