You are absolutely correct, three RGB with sync on green is not the same as three wire component. Does anyone know in theory which one is better. Key Digital makes some relatively inexpensive rgb to component and component to rgb converters. They work real well and have a retail price of under $200 each.
The issue of BNC, RCA, VGA connectors is quite different. According to Extron in product training, a VGA connector because of the small wire sizes involved and other factors is not a high quality connection for high quality video. It is used because it is cheap and takes up much less space than multiple BNCs and RCAs. The primary advantage of BNCs (besides their locking ability) is the constant 75 ohm impedence you get. RCAs are generally 50 ohm. You can arque all day whether a 25 ohm difference makes any difference. Most consumer goods use RCAs and not BNCs.
