Tools used: DvdReMake.

Some DVDs have a menu screen on startup asking to choose aspect ratio or language. Depending on the selected menu item corresponding part of the DVD will be played. Often customized DVD backups don't contain complete DVD content and it is desired to have one of menu items "selected automatically" without presenting a selection menu. Here is the procedure on how to do it (it is assumed that you've already ripped your DVD to the HD):

Step 1. Start DvdReMake and import directory with ripped files (browse your HD for the folder, then when you see all the dvd files press the select button).

Step 2. Find menu of interest. Most probably it is one of the blocks in VMG. If not you need to check menus in other TitleSets.

Step 3. Right-click on needed button and select "bypass menu". Program will do all the needed modifications automatically so that disk will play as if menu was presented and button was manually pressed.

Step 4. That is it. Export DVD (or use "export test DVD" to export just few seconds of each chapter) and play to test. Use any software DVD player you have. You should now have your movie of choice playing. Note: Some DVDs may have 2 aspect ratio menus. Look through your disk to ensure that it is not the case, but if you will find a second copy - no worry, just repeat the procedure for this menu as well.
