Your setup is what I'd call an overkill! ;)
You probably got this: http://lightberry.eu/ ?
Too many single components for my taste.
Having an all-inclusive solution like this one with a dedicated FPGA makes much more sense to me.
Unfortunately it seems that a high res solution is never going to work for all use cases due to HDCP, processort speed etc, and it will probably never launch commercially because of Philips' ambilight patents like EP 1379082.
I've been looking for an in-between all-in-one solution which takes HDMI as an input for the past years, but there's no real reasonable solution which I would take.
The best I saw to this date is this: http://www.keiang.de/Content-pid-32.html, but unfortunately it's not publicly available (he didn't release the circuit diagram and the list of electrical components needed, at least the last time I researched the site).
Mine isn't a lightberry. I just use the usb video card plus the Pi.
Also, an HD signal as input to the ambient light setup just isn't necessary. The software (or FPGA) is going to average pixel colors around the border to effectively reduce the resolution to match your LED spacing. With an HD signal, you're just spending more processing power/time to filter out and throw away more information.
