NO WAY am i going to play movie audio through some all-in-one "AV receiver" ! ... Have any of you used an HDMI DE-EMBEDDER....
You could consider a high-end pre-pro. A McIntosh MX160 would likely solve your problem, and deliver "the highest rez," but for a price...
I test-drove a Meridian HD621 and it worked great, but it also required a dedicated Meridian prepro in the mix. The HD621 is possibly the best de-embedder/switcher available, but again that high quality comes at a high cost. And, for me at least, Meridian's "customer service" was more than a little alienating (but I can save that for another thread).
