I have the SPMC 12.4.1 installed and DTS passes through on HDMI. This is the build with video issues, though my video really doesn't stutter very much. The working video build 12.3.x didn't provide me with surround options.

It's good to know that it's possible at least. Someday, we'll have a build with a perfect intersection of all the good options. With DTS bitstreaming ticked off, my fingers are just crossed for Blu-Ray-quality remuxes working.

have you seen any android boxes play bluray remux files? I've tested it on Ouya/Mojo and the firetv and they all stutter with xbmc for ouya. spmc and gotham v13 beta 3.

My HTC One plays all my Bluray rips (except the landing scene in Saving Private Ryan, which is apparently bottlenecked by the wifi) flawlessly using Gotham beta3, over wifi. The HTC One has a 1080p screen, and specwise seems identical to the FireTV AFAICT (Krait 300, Adreno 320). So the current issues with the Fire TV are mostly likely software related.
Though, it is somewhat disappointing that the Krait300 cpu isn't capable of pure software 1080p decoding.
