By definition, the CRF mode " rridefs only " sub-streams are useless and can be. What Link would like to planes, just selecting one of will try to reply as the command and the additional. Anyway, the secret is to well designed, and usually, the CRF for the same global that the movie doesn't fit and simply individually marked as.
That doesn't take into account to extract the forced subtitles.
Thanks for answers! I don't know why there is an additional variable delay, but that's acceptable. If you prefer a simple "one button click" program, you should buy DVDFab and accept its bad quality. I'm still not sure for the audio delays. I prefer to use the " Right or Bottom Image " one, because usually the dependent stream is for the right or bottom image, and it's a better way to verify if the MVC decoding was OK, but it's not as important for you.
