I have just bought an AV amp which has an HDMI out to my HD tv. MY DVD player does not have an hdmi output. Should I use its component output or s-video output through the amp or leave the scart cable straight to the tv? Never really known the difference between s video, component, optical or scart!
These standards arose out of the need for backward compatibilty. A luminance signal is required for black and white TVs. A scart was designed to transfer RGB, which is potentially capable of the highest quality, and composite. It is now sometimes used to carry S-Video. Usually only the AV1 scart connector on a TV will accept RGB and your DVD player may not provide an RGB output. If you have the cables for component video, I would suggest that it is worth giving it a try. Otherwise, if you are satisfied with the scart connection, the stick with that.
