I want to use an external screen but my VGA input of the external screen is already busy by another computer, so guys tell me if YUV is as good in terms of quality audio/video than VGA ?

Inch allah ?
VGA is a hardware interface/connection. It uses RGB color space.
YUV is a color space, not a connection, and also has nothing to do with audio.
What other video connections are available on your external display (other than the VGA input)?
When you say "has nothin to do with audio " , do you mean u cant obtain audio with a YUV ?
Other input is S-video ...?
If your external display only has VGA and S-video inputs, then you will need a VGA switch (like one of these) to connect two computers with VGA outputs to your single display.
It is possible to convert a VGA output to S-Video with a converter (like this). However there will be significant degradation of the video quality. S-video is only standard def at either 480i or 576i resolution. At 480i (NTSC) the effective resolution is only 720x480 pixels and the S-video signal has considerably lower color signal carrying capacity than VGA..
You have not identified what model Mac you have, but if it's any recent Mac there are no adapters that can directly convert DVI/miniDVI or miniDisplayPort to S-video anyway. You would be doing a double-conversion from DVI, miniDVI, miniDisplayPort to VGA + VGA to S-video, resulting in significant loss of quality.
VGA and S-video are video interfaces/connections. They do not carry audio. Audio is a completely separate interface/connection.
