Thanks for the explanation.
I had always thought that the
Preview graph has not been built error was unique to MC as I do not recall seeing it when running only the ATI TV.
However, my ATI A-I-W 9600 Pro has a wonderful integrated FM radio tuner that is built right into the TV module (the little silver box on the video card).
What I am beginning to think is that the FM radio might be using the same device driver as the TV. Also, this may be where the error message comes from; possibly a minor conflict between the FM radio and MC TV when switching from ATI FM radio back to MC TV.
It does not happen all the time, seems to be more random then anything.
What do you think ?
