Also looks like a really neat possibility for a front-end MythTV box.  The
lowest end claims 0.65 Watts TDP!

BTW, Intel is calling the combined North+South bridge an "SCH", or system
controller hub.  The first one is numbered "US15W":

An additional, informative writeup can be found here:

BTW - this article specifically mentions Blu-ray.  Here is a links the most
concise explanations I could find on "converting" frame rates:

http://en.wikipedia.org/wiki/Inverse_telecine#Reverse_telecine_.28a.k.a._IVTC.2Finverse_telecine.29

In short, I don't think the frame rate will pose any problems.

Have fun,

P.S. I suppose I should use this post to also introduce myself: I'm an EE with
ten years of high speed FPGA and PCB experience.  Since it is my profession, I
obviously have access to licensed tools (stuff like Orcad, Allegro, and Xilinx
ISE) that could be used for side projects.
