The component video spec is a maximum of 1080i/60. However, there are many devices that will send 1080p/24 out component cables even though it's technically not supposed to be done, and most newer TVs will receive and properly display such a signal even though they're not supposed to. 
Besides, there is no 1080p/24 programming on U-Verse, and the U-Verse box couldn't send a 1080p/24 signal if there was. So even if you use HDMI, the maximum you get out of the U-Verse STB is 1080i/60.

I had an email conversation with an engineer a couple weeks ago. He said that our HDVoD is broadcast in full 1080p, but that's it. Everything else is 1080i.
I also just got a new 65" Mitsubishi DLP HDTV (WD-65737), which is why I was asking my friend aobut the HD broadcast, and I CAN NOT WAIT to get home and try the calibrations listed in this post. I started with Tweak.com's reccommendations and have not been thrilled with the result. It now seems way to dark, or "crushing blacks", as I've read on this post. I also got caught up in the HDMI cable frenzy. I still have plenty of great quality component cables in my closet (Cox doesn't ask for them back, my installer left me extras, and I also have a good friend that's an installer) so if the adjustments don't work for HDMI I'll go back to them.
Thank you all for posting this plethora of information!!! I will take all of this info and hopefully get a great picture with my new TV.
Thanks,
