any time a step may be omitted from processing may result in a slight improvement .
however, "converting" is a process and there is always an inherent loss in the process.
the original reason for using the S-video on a tv was to feed seperate luma and chroma signals
directly into the set . the reason this resulted in pic improvement was it bypassed several conversion steps .
rf signal to if sig, to detected raw video w/sound to seperate video , to seperate luma /chroma processing and on to video drive out to crt......
many mfgrs simply tied the luma/chroma together at the jack and then off to processing - thus, defeating the original purpose .
btw, it is NOT unusual to find "creative" spelling on forums. a carry over from text messaging

besides, english may not be their native tongue....and then there is the dreaded " TYPO"
