Motion Enhancer/Detail Enhancer and Wall Mount Questions (XBR4 owners)

[PNF]

Well, I posted on the question in that mega XBR owner thread, but no response, so I'll start a thread here

1) I was watching Troy again on blu and I noticed that in some of the actions, the residual motion image is quite noticeable, so I am wondering what is it that reduces the residual image and whats the con/pros of it? I am thinking its the motion enhencer, so I reduced it to Medium/Low, but still there a bit, but not quite as much.... I have calibrated based on some professional calibration settings I found on the internet and also in that XBR owners thread, so I think it is pretty well-calibrated at this point.

Also, those detail enhencers, do they really work as I dont think i have seen too much of a difference yet.

2) wall mount, what do all of you 50" plus TV use to hang it. I have those standard dry walls behind the TV, so I dont think it is that strong or at least I dont trust it. I'd very much like to hang my TV, so just wondering what do you guys use to mount your 50+ inch TV that weigh 100+ pounds. (Some pictures would be great!)

Thanks
