I have previously using the following flow to create HD .M4V files from .MKV DTS HD files. 1. Use Moyea to convert DTS to AC3 2. Use MKV Merge to create a new .MKV 3. Handbrake to .M4V 4. Subler to tag What I am now thinking is do I even need to do step 2?? Can't I just Handbrake the original .MKV file and just have track 1 audio as DPII from DTS and then after the Handbrake file is created can't I just see then mux the AC3 file made from Moyea with Subler so I don't have to create a new MKV file? If this is true is there any problem with over 4GB files? I didn't see the options about 64bit chucnks in Subler people referred too. Thanks.
