I'm doing the Defense of Whiterun mission for the first time, and she has scars and a totaly different hairstyle. Her face looks altered aswell.

I noticed a similar change today, but i think it was because i switched between low def and high def tv.

Really? Huh, that's strange. I have my Xbox connected with a component cable seeing as the Hauppauge HD PVR does not allow HDMI cables.

There's three different versions of her apparently.

I noticed the same a few weeks back before dawnguard came out. I dont think dawnguard changed her apperance. I think it might be a glitch or something regarding that one mission as she appears the same for me before and after.

Lots of things look different....once you attach HTMI(from a Zune works pretty good on plasma)
