The aspect ratio can be modified via the settings- or context menu. In a sub-menu you may select one of the following aspect ratios:
4:3, 14:9, 16:9 (widescreen) and 2.35:1 (cinemascope): These options will override the original ratio of the broadcast. You should use this when the automatical selection fails to display the picture correctly. It may be also necessary for the playback of cropped videos or AVI files.
Auto: The DVBViewer automatically sets the aspect ratio according to the data transmitted with the TV picture. This is the default setting, which will give good results with most broadcasts.
None: The DVBViewer does not adjust the TV picture. Instead it will fit the DVBViewer display-window, probably resulting in wrong proportions.
Best Width: adjusts the width of the picture to remove the black bars (letter box).
Image Position and Size (Zoom)
The zoom command in the settings menu lets you adjust the position and size of the TV picture with four sliders.
You can move and stretch the TV picture both horizontally and vertically to completely fill the window and eventually remove black bars.
The five radio buttons down left enable fast switching to different window sizes ranging from mini television to display-filling size, whereby the aspect ratio is preserved. The context menu offers the same functionality with the zoom command
The Default button resets all adjustments to the standard setting.
You can pre-set 3 settings with the "recall"-button.
Of course you may also resize the DVBViewer window by left-clicking its lower right corner and dragging it to the desired size. In this way and in combination with the "none" aspect ratio setting the picture can be adjusted to any desired proportions.
