In DVDFlick, import your two videos. Click on Project Settings, then create a title for the entire disk. If the rest of the settings are correct, then click Accept. Go to Menu Settings and select a background that has Select Title as one of the options (in other words, not one of the simple ones). Click on Preview. While there, click on title and title select in the drop down box to make sure both videos show up. Close that window and hit accept.
Now on the right side of the main window click on edit title if you want to put chapter points in each of the video titles you have imported. Once set there, you are ready to click Create DVD and start the encoding process.
