Keep Karaoke Window Open simply keeps the Karaoke Options window open
even when a Karaoke file is not currently playing.
Disable Gap-Killer makes sure that VDJ does not skip leading silence on
Karaoke files. Many times you need the introduction on the screen before the
music begins to play.
Allow Custom Backgrounds - this option allows a Karaoke Zip file to have a
custom background image embedded inside. Simply place any .BMP, .JPG, .GIF
or .PNG file inside the Karaoke Zip file, and it will be displayed behind the lyrics
when that file is played back.
Use Smooth Image Resizing - This option does a nice anti-aliasing when the
Karaoke image is resized (for example, when displaying full-screen).
This option utilizes a lot of CPU, so you will need a fast machine and good video
card for this to work nicely. Also note that, when used on a television, the
difference is negligable. It is usually not worth the extra overhead when using a
television.
