When you create a new project, click the Settings button on the New Project panel. This will open up the panel from which you can select a project settings preset.
Are you still working with video from your JVC or are you editing video from your Sony cam now? That will determine which project settings you select.
If this is AVCHD video from your Sony, remember that version 10 does not offer AVCHD settings for 1080p, so you'll need to shoot video for this version of the program in 1080i.
