The MPEGLA.COM is at the root of all this. MPEG-2 is not free so your ire is understood but a little misplaced.
Purchased this some time back and every time I made an upgrade, it disappeared off the dock and also Applications.
The Apple store re-installed it for me promptly because I had a purchase order number as well as a case number.
After upgrading from one cat to another (I think it was Snow Leopard), it was lost again. This time the Apple people had deleted the records of my original purchase and subsequent re-installation and would not recognize the numbers I supplied as proof and refused to issue a new component.
Without that applet I cannot make iMovies from videos taken with my Panasonic camcorder and had to dust off an older tape-based one.
Rather than sending another 20 bucks to Foxconn in China I will do my future editing on my wife's Windows7 machine or even the old WinXP in the closet. Upgrade to the next feline is out of the question.
My next computer will NOT be an Apple.
