I just received my 50V500 yesterday. I am totally satisfied with it out the box with just alittle tweaking. I also had a center channel mounting problem til I decided to mount a shelf just above the set. If you can not or do not want to mount a shelf, I ran across a set top shelf from Sanus for $30 you can get a Crutchfield or your local electronics shop. I was not sure it would work on such a narrow top set like mine so I opted for the shelf. I hope this helps. I have a thread showing how I mounted my center channel.
