Video clips out of dimension...help

[linardni]

Using Canon Powershot A430 I have shot a 640X480, 10fps AVI videoclip and burnt that in a CD through Nero. The output CD contains an autoplaying DAT file. However the video dimensions are out of screen with considerable loss in video quality. What to do so that the video quality remains intact and the dimensions of the clip fits on screen when viewed through CD players?

I think when u r converting it to VCD, there will be loss of quality....

But how will I make the video fit within screen?

Is there any resolution related things while playing it in CD Player??
I think Only aspect ratio...

I am too not clear ....
