Thanks very much for your detailed reply, satanika. Honestly, I couldn't say that could discern any issues with your 5.1 track. It just has a different feel, as expected. I'll do some more listening tests to see if I can pin down the difference in a way I can explain better. I may also try to see if I can replicate your process with the unedited DC48 track + LFE.

I haven't listened to the DTS yet, but maybe I will try that to see if I can hear any difference. My original audio-only listening tests were done as AVCHD on SD card, which isn't compatible with DTS on my player (at least, I don't think this is is). I know the 1.5 Mbps track won't fit with my video bitrate, but I may be able to squeeze the 640 Kbps track on the disc.
