In order to get rid of letterbox thing I clicked off of maintain aspect ratio in event properties. It looked great. After rendering to "print movie to DV" error message occurred. "An error occurred while printing a file to the device. The file format is not correct for the current device." When I had rendered the project earlier with the picture too tall and squished it printed to tape fine.
Project properties are: NTSC DV 720x480 Pixel aspect ratio 0.9091.
Event properties are: Maintain aspect ratio off, playback rate 1.000
Should I set pixel aspect ratio to 1.000 in project properties?
