Apple DVD player. All other questions has to be left to a computer Mac experts
. When you deal with Mac all your life, video card never has to be dealt with. Everything is just given
. So sorry if I can't give you a breakdown.
On regular DVDs, you can't really tell the difference all that much other than lighting, contrast, and color that you can adjust on your TV but not with Apple DVD player. However, for my burned DVDs, all the artifacts are more obvious. I even turned the contrast all the way down. I guess higher resolution could mean higher resolution of all the artifacts also.
