Options OSD General
 Overscan adjustment
Overscan adjustment settings cause OSD pages to get moved towards the center of the window in order to compensate possible overscan of your television set when using a TV as monitor.
Overscan means that the actual edge of the picture is outside the visible viewing area of your television. For actual TV programs Overscan usually doesn’t matter much, especially since TV stations already do take overscan into account and avoid putting anything important close to the edge of the screen. Edges often are kinda blurred or black to begin with, so a bit of overscan is no big deal.
For the OSD, however, overscan is a rather annoying issue, since some OSD elements might get cut off or do not show up at all. Moving the OSD a few pixels towards the center is usually enough to fix this. But the downside to moving OSD elements around is if your OSD skin of choice is using a fixed background wallpaper graphic. With overscan compensated, OSD elements might no longer appear at the exact position the OSD skin designer intended them to appear at and therefore the wallpaper background graphics might not match the actual location of your OSD elements, leaving the impression of it being offset by the amount of pixels you entered to compensate the overscan. Most commonly these issues can been seen with the small live TV preview window.
We do not have a fix for this yet, so if your OSD skin is using a background wallpaper graphic you might want to consider not using the overscan compensation, try disabling the background graphic for the OSD, or even try a different skin altogether.
 Quality Settings
These settings control the display quality of the OSD. It is advisable not to set the display quality too high, since high quality settings in combination with high screen resolutions could cause a lot of CPU load possibly slowing down the OSD or even your system, in extreme cases to a crawl even. Our tests have shown that the actual gains in display quality for the OSD from using more sophisticated settings here were rather small, the most important factor for display quality of your OSD is the video renderer in (Options DirectX). If possible, use one of the custom renderers there.
 OSD Behavior
 Close OSD on starting audio playback
This setting controls the Audio OSD screen. If this box is checked the OSD screen will close automatically once you’ve selected a song for playback and playback has actually started. If this checkbox isn’t checked the OSD screen will remain open, this is usefull for example when creating a play list.
 Close OSD on video playback
This setting controls the video/tv playback OSD screen. If this box is checked the OSD screen will close automatically once you’ve selected a video or channel for playback and playback has actually started. If this checkbox isn’t checked the OSD screen will remain open, this is useful for example when creating a play list. If you’re using DVBViewers recording feature it might make sense to have this checkbox checked. Once playback of a video starts the OSD closes automatically saving you the need to press another key or remote button to get the OSD out of the way.
 Show logos in Channel list
This setting turns Senderlogos in the OSD Channel list and MiniEPG on or off. For channel logos to work your chosen skin needs to support logos as well. If you didn’t install any logos no logos will be displayed. If your skin expects logos and this setting is disabled, there will be b lank areas in your OSD where the logos should been.
 Hide known extensions
If you check this box a files file extension (like .mpeg or .mp3) will be hidden if there’s is a default program assigned to it for opening/playback.
 Use cutout frame
This setting only has an effect if you’re using Overlay Renderer as video renderer in Options DirectX). The overlay renderer basically works by filling the player stage area with a dark purple color and then telling your graphics card to replace that purple area with your video output. In certain circumstances this purple fill color might bleed through areas that are actually supposed to be deeply black. Examples include: playing a video with an aspect ratio that doesn’t fit the current window size/aspect ratio or when no playback occurs at all. So if you’re using Overlay renderer and you’re seeing purple areas you want to get rid off check this checkbox and DVBViewer will cover the purple areas with black.
This settings controls after how many seconds without any user activity an OSD should close itself automatically. If you set menu timeout to 0 the OSD will never close itself automatically. If you want to set a timeout for individual OSDs use Windowdef.xml.
 VRM Transparency
Use this slider to set the overall transparency of the OSD. (OSD skins also support areas with individual transparency settings not influenced by this slider). If you chose ‘Overlay’ as renderer in Options DirectX transparency will not work.
