I'm looking to not convert any video or audio but simply use a PassThru option to copy over both Audio and Video streams from DVD's and such. I'm aware VisualHub has both but it can't create .MKV files for movies that contain .DTS audio. Does anyone know of a program that can do this? It doesn't matter if its Mac or Windows only. I just need something to help me build my all digital media library. As far as I know .MKV is the only container that can have two audio tracks (english as track 1 and spanish as track 2) as well as subtitles within the container. So that is why I need .MKV output, so can anyone help me with this?
