The deviation is about 1 MHz and the maximum frequency recorded on a VHS tape is a little over 5 MHz (Beta is slightly different and S versions of Beta and VHS extend some of these to achieve higher bandwidths. The color signal is separated from the composite video and is amplitude modulated on a 629 kHz carrier. This is called the "color under' system."

Thanks, interesting !
It means that a lot of people on several forums are wrong about that subject because all research I made (maybe not enough !) lead to the information that VHS record a composite signal.

Ok, but as my VCR does not have S-Video output but only SCART, and as the manual does not mention if this SCART can send a s-video signal, how to know what signal is sent on SCART to the dvd burner ? Could it be RGB ?
Let's admit that this is CVBS ; in this case I still have to know if the Y/C separation by the dvd is useful or not.
That's why I gave some extracts that can be analyzed.
