A curious thing happened to me for the first time...
After encoding with Ripbot, which accepts only one audio track - in which case I choose "AC3" to be automatically encoded - I tried to add too , DTS 5.1 track using mkvtoolnix v 4.4.0, last version from November 7, 2010.
After remuxing I checked with MediaInfo and it appeared as DTS track has NO 5 channels but only one channel ... I did more tests but all results were the same = DTS was taken as a mono channel and not 5+1 channels .
I had to demux all video and audio tracks and using Megui muxing options I remuxed audio and video tracks, which gave the expected and correct result.
My question is if I made a mistake somewhere or if the new version of mkvtoolnix gaves such errors ...
Never until now no such weird thing happened to me with mkvtoolnix. For instance " mkvmerge v4.0.0 ('The Stars were mine') built on Jun 6 2010 " worked ,but " mkvmerge v4.4.0 ('Die Wiederkehr') built on Nov 7 2010" makes me troubles.
Where am I wrong ???
