TBH, if your DVD player doesn't support scart (even the most modern of TVs still support a scart socket) or HDMI then you're better off replacing it than trying to mess around with converters.
Component is an analog signal, hdmi is a digital signal and typical need digital rights management. Don't wast money for an adapter that will not work or give you bad quality. Spend the money for a cheer new DVD player with hdmi out instead.
