CX 900 question - how to change to 1280x720?
 

When I bought my Sony CX 900, it was recording in 1280 x 720. I liked that very much. Great for me. But for some reason, recently it changed, and now it's been recording in 1440 X 1080. I don't like this resolution. How can I get the 1280 X 720 back? I have 60i selected in the frame screen. I don't know why the resolution changed.
