Haha, no, not at all!  I'm grateful for any feedback and what you've
mentioned so far has been a great insight to the issue!  As for
waiting for a faster computer to solve the problem... we have the
latest and greatest Mac Mini running a Core 2 Duo 2.0GHz machine.
Others running 2.4GHz Core 2 Duo iMacs have reported the problem.  VLC
plays back 1080i/p content with all of its fun bells and whistles
without a hitch on less powerful machines than even the 2.0GHz Minis.
Frontrow, whilst arguably not shifting a picture, can playback 1080p
encoded files to 1080p plus monitors without a hiccup as well.

Not sure what's going on but this seems... abnormal.

Thanks for the help, though!
