My comments:
The claims on this product are not entirely correct and many people seem to confuse this kind of cables to real converters (I have received several mails on this ans answered questions on several forums regarding those).
This cable does not do any signal conversion at all. This cable just connects S-video and TV RCA connectors to certain pins on VGA connector (RGB pins) that can be defined to send besides standard VGA signals also the video formats those S-video and TV RCA connecors shoudl carry. This kind of adapter works only on some video cards that have built-in VGA to TV conversion circuiry that works in such way that you can configure the card to output either standard VGA signal or TV S-video/RCA signals from the VGA connector. This kind of cable work only on some video cards (at least Matrox dual head models), definately not with most video cards on the market.
This cable works as advertised only for those who have a special video card that can be set to output TV signal from VGA connector. Most video cards do not support this special extra non-standard feature. Thsi kind of adapter does not with most video cards, at least most of the cards I have used over the years.
For all other uses (VGA signal conversion etc.) you might think this kind of cable is completely useless and waste of money.
