Hi - I tried this for the first time last night. (i also searched the forums and didn't spot anything directly on point). Anyway, I tested the mkv with VLC this a.m., H.264 compression - video looked great but it had the audio narration. I had selected english subtitles, with a default of lossless and a default of i think 5.1 (since right now, that's all i have) - movie is Life of Pi and as mentioned, I got either the narration version or the director's narration. There are a zillion streams to choose from. It defaults to selecting I think the second stream. When I use CloneBD's preview, it seems to force the captions (or maybe that's built in, as parts take place in India, etc.) and I don't think I heard the narrations. I don't know if there is something else I should try other than maybe just hitting the other streams (which all seem to look the same, act the same on preview, etc.) Lastly, I THINK If I use mkv I lose the Bluray top menu, and chapter menus - is that correct, or is there a way for me to preserve? I'm not interested in the coming attractions, and not interested in burning back to a disc - I'd like to stream either with Kodi (which seems to be working meh) or possibly Plex. Any advice on playback would also be gratefully appreciated - thank you so much!
