Hi, Lately my quicktime has stopped working properly ( v7 ). The videos i play won't display anymore, only the audio works on some live stream but with no display. On mostly everything i try to view through quicktime a Quick time question mark appears and the live stream doesn't play. this started a week ago with no apparent reason for this happening. I don't know maybe i did something to cause this, but i don't know if I can change the default settings in a way to fix quicktime directly, or, if maybe its something to do with something else. I tried re-downloading quicktime stand alone player but the same problem persists. any help or recommendations you can give will be very helpful. I posted this on other sites but no one writes me back. thank you.
