Jack - I have the Samsung HLN4067W and it has a built in shelf on the top (though not as wide as the VP150). I had my VP150 on it for awhile and didn't notice any bowing of the TV cabinet.

I've since moved it to the bottom shelf of the TV stand (I'm using the Samsung stand) with the VP150 flipped so that it is angled upward.



It's out of the way and the wife likes the placement. I haven't noticed any difference in performance vs. the top of the TV.
