„ Decoder delay : this parameter is associated to the decoder buffer.
Increasing this delay improves the quality. However, the zapping time
is longer.
„ Deblocking : enter a value to define the strength of the deblocking filter
that will be applied to the stream. This helps to prevent the blocking
artifacts resulting from image compression. Disabling the deblocking
gives a sharper image, which might be a good choice when the video
bitrate is high.
„ Closed caption : set to Insert closed caption if you want closed captions
that are present in the incoming MPEG-2 video stream to be collected
