Related to my other question, is HDMI output from a DVD player good/bad/neutral?
It all sort of depends on the hardware, but really, it’s fine. Component is fine, too. Consider the OPPOs; they are somewhat flimsily built, but they are feature rich and do decent upscaling for not much scratch.
Ninja Edit: I said “D/A converter,” then realized how retarded I am. The point remains: HDMI is fine with DVD.
Second edit: I would make a shitty ninja.
HDMI works just peachy, and it’s nice to get all the signals in one little cable, but it’s not really necessary. On a DVD, I can’t really see any visual difference between HDMI and component with DVD as a source.
