If you use conversion from Full HD (1080p) to DVD (480p/576p), please set this option:
Settings -> Processing -> Resize - Type = Super (for higher quality).
If you are not satisfied with DVD quality and need menu and chapters, you should use conversion to Blu-ray, but it will require a more expensive DVD/Blu-ray drive, BD-R/BD-RE discs and Blu-ray players. Therefore, I recommend you to convert Full HD video to most popular MP4 format with Full HD frame size (1080p) and set starting JPEG slider as cover. Then you could burn that MP4 video with nearby JPEG file to DVD disc as Data DVD with AVS Disc Creator.
