Description
Set to Yes to minimize error in case of packet loss
(for example, due to network congestion).
If set to Yes, a Flow Control (bandwidth reduction)

errors before video is frozen.

Error strategies field is set to Yes. Drag the slider to

synchronization (strongly recommended setting). If
set to No, adjust manually by dragging the Delay
slider until you obtain the best synchronization.
