Had to thumbs up that one.
Especially since it came after the 100" screen post.
I've got the same intro's Mark has and I agree, they do have a huge wow factor. The videos can be made in a matter of minutes from this website: http://ivipid.com/
The create charges about 2 bucks per video if you get the larger credit package. Small fee for what you get in return.
I use the Cinema Experience app in XBMC to launch these intro videos and pull trailers in 1080p from Apple Trailers website
My biggest wow factor on my home theater setup is my boblight add-on. I know it's small time compared to a lot of the setups here, but I still enjoy it's wow factor.
