Q: The strange thing is, is that this didn't used to happen. Some time ago, I was deleting old files and stuff that I never use and I'm wondering if I accidentally deleted something related to Quicktime. My computer is an iMac 0S X 10.3.9
A: That's because 2 reasons...or you don't have you video card driver installed prperly or you don't have an encoder...I suggest you to download nero 8 or BSPlayer!
