Adjust DVD Aspect Ratio for 1:1 Pixel Ratio (you should leave this on)
DVD Resolution is either 720x480 for NTSC or 720x576 for PAL. Either resolution does not conform for display on a standard display device. By default Zoom Player compensates for this automatically. However, with this setting you can disable this compensation. It is recommended that you leave this setting untouched, even if you don't use a 4:3 display device as even 16:9 or 1.85:1 devices require their sources to be originally set for 1:1 pixel mapping (and then later adjusted for 16:9 using the Source Relative Stretch aspect ratio value).

Auto-Load Selected bookmark on Play
Within the bookmark editor, you can select a bookmark and assign it as an "Auto-Loading" bookmark. This is a done by prefixing the bookmark file name with "AutoLoad.". If this setting is enabled, then the AutoLoad bookmark is automatically loaded when the disc is played, allowing you to skip the menu system entirely and get directly to the movie.

Auto-Save / Load Disc Position on Stop
When enabled, the Disc's last position will be saved automatically the next time you stop playback. The next time you play the disc, you will be prompted if you want to resume from the last saved position. If an Auto-Load bookmark is present, you will be able to select to resume from its position instead.

+ Confirmation Dialog (otherwise disc position will override auto-load of selected bookmark)
When enabled you won't be prompted to resume from the last saved position. This means that if a last saved position mark is found, playback will be resumed from that position automatically. This will override the Auto-Load Selected Bookmark setting.

+ Auto-Close Confirmation Dialog after 10 seconds
If this setting is enabled and no user input is given within 10 seconds, the confirmation dialog will close automatically.

+ Limit Auto-Loading the last disc position to the last disc played
If the Auto-Load Disc Position is enabled, you can have it limited to only Auto-Load if the disc you are trying to play is the last disc played. Otherwise the stop position of all discs will be remembered forever.

Auto-Save Disc Definition File on Stop (color controls / aspect ratio / etc...)
Similar to the Media definition files, you can have the disc's settings saved automatically. The information that is saved is controlled by the content of the "zplayer.zdf" file (same as Media Definition files). If this setting is disabled, you can still manually save the data (using the "save definition file" keyboard macro) so it can be loaded at a later time.

Auto-Load Disc Definition File on Play
You can also have the disc definition file Auto-Loaded. You should probably keep this setting enabled if you plan on having a per-disc setting. By default the information that is saved is the Video Position (width/height/offset), The Video Aspect Ratio and the Color Control values.

Auto-Disable Subtitles
When enabled, Zoom Player will try disabling the DVD Subtitles if subtitles were on by default. Please note that some discs prevent you from disabling subtitles and there's nothing that can be done about that other than re-authoring the disc content.

Auto-Disable Closed Captions
A lot of movies have closed captions enabled by default. When this setting is checked, Zoom Player will try to automatically disable close captions when a disc is played. Please note that this won't work on movies that force subtitles as Closed Caption is not the same as the subtitle tracks.

Set Closed Captions Background to Transparent
When enabled, the Closed Caption background will become transparent against the video (rather than a black box).

Brute-Force apply Color Controls values every second
In some cases, the Color Control values may be lost due to driver issues. By enabling this setting, the color values will be applied every second.

Show DVD Background image (when stopped)
When enabled, Zoom Player will look for a "dvdimage.bmp", "dvdimage.jpg" or "dvdimage.png" file in its program directory, if one is found, it will be displayed while Zoom Player is in DVD mode with nothing playing.

Assume DVD Menu at all times (prevents using the arrow key functions while a DVD is playing)
Some DVD titles may have bad menu identification codes which may prevent Zoom Player from navigating the menus. By enabling this setting, Zoom Player will assume that it is navigating a DVD Menu at all times. Since the Arrow keys are used for both functions and menu navigation, this setting forces the arrow keys to function only with Menu Navigation.
