[FFmpeg-user] "Residual encoded channels are present without core"

[tlum]

Hopefully I have a simple question. I was trying to copy an (DTS-HD MA) 
stream, but the result was "Residual encoded channels are present 
without core".

I was under the impression the core DTS packets are commingled within 
the stream and that FFMPEG doesn't know the difference without a 
bit-stream filter. So, I was expecting to end up with a replica, but the 
message suggests that either the extra core packets got dropped or there 
is something else damaged about the copy.

I just wanted to validate my understanding and correct my expectations 
before I waste any more time out of ignorance.

TIA
