I didn't know that they digitally erased the hole under Lance Henriksen on the Blu-ray. I vaguely remember Cameron speaking of that goof on the DVD commentary, and that he said that the way it's shot, you're not supposed to look there, so that's how he justified it. Now, I'll have to listen to the Blu-ray commentary to hear if it's still mentioned.
Why can't directors keep their movies the way they were? I'm beginning to wonder whether the digital technology is a blessing or not. Well, obviously it is, but it turns some directors into morons. Vast subject...
The fact that the first thing you said was "I didn't know..." tells me it was a successful digital fix, for what it's worth. I never knew about it either, but I'm glad they fixed it. It's such a small thing that I would never request an "original version" to be included where the hole still exists, just for the sake of having all previously released versions. What would it be called, anyway?
"Aliens: The Complete Hole Edition" ;P
