TVStandard HD720p isn't going to fly with TVOutFormat COMPOSITE.
Composite video is maximum 720x480, interlaced. You'll have to set
TVStandard NTSC-M with Composite. To use the HD720p (or any other HD*
option), you need to be outputting via Component video. DVI, VGA and
HDMI, everything should just behave like its a monitor (at least, my
HDTV has always simply been fed via DVI like it was a 1920x1080p
monitor).
