HDMI is such a mixed-bag, isn't it?
On one hand, you have more convenience with less wires.
On the other hand, you have copy-protection/handshake issues with the displays.
I think everything should come with both HDMI AND Component Video + Coaxial Digital Audio. Then at least we could have the option of using Component 1080p.
HDMI is capable handling 480, 720, & 1080 resolution.
On my "older" Sony HDMI v1.0 DVD player, I can set the resolution to 480p and still get picture when hooked directly to my "older" HDMI v1.0 TV.
