To clarify we filter the DTS core out using libavcodec not using your
receiver. At this time bit streaming DTS-HD using libav isn't possible
anyways. The bug in mythtv was that it tried to decode the DTS-HD
extensions which it doesn't support causing "bad" things to happen. So
yes you should be able to play a DTS-HD track in mythtv and it
passthru the DTS core to your reciever via SPDIF.
