Hi jp....
I was one of the first on the forum to get this lcd, so I'll try to address your questions:
DVI = HDCP? -> I don't believe so (not mentioned in any documentation and I have no way to check it)
Component video = HD capable? -> Yes indeed. It supports 480i/480p*/720p/1080i
* there are some issues with the 480p input..
Wall mountable -> Yes. Not all wall mounts will work. I'm using an Omnimount CL articulating lcd wall mount...works great
Burn-in Problem? -> well, basically at this point lcd/plasma type displays are prone to some burn-in of some sort. I haven't had problems with my W1700, or my panny plasma, but that doesn't mean that it couldn't happen
Upconvert all to native? -> Yes. This is the nature of fixed pixel digital displays (lcd plasma etc). What you see is what you get.
And yes, I like my set...I have it installed in my rec-room / bar as a "remote" screen for my theater (different room). Get up to get a drink, and the movie is still playing...
480p problem: I (and other users) have experienced problems with 480p input via component. The video suffers from what can only be described as stuttering or jerky motion. This unfortunately happens via several sources (tried HTPC, cable box (HD), and dvd player...they all stutter). My solution? Use 720p and 480i for everything.
Anyway,
Cheers,
Rich
