Why does the component / YUV input not work, when the CV/YC (PAL/NTSC) inputs do, when playing from a DVD?
Answer
This may be due to the Macrovision protection system, which adds extra sync pulses and video peaks to the signal.

Whilst this protection system is present on all outputs from a DVD player when a copy-protected disk is being played, the scaler's composite video (CV) and YC inputs are decoded by a chip that can ignore these pulses and peaks. However, the scaler's component / YUV input cannot, which results in either a very poor signal, or none at all.

Since there is not a lot of benefit in using a component / YUV signal from a DVD over a YC signal (because of the video compression used in the DVD format), it is suggested that YC is used instead - this also allows many of the sharpness / colour adjustments to be used.
