How to strip audio or subtitle tracks off a Blu-Ray Disc

[ppeterr]

I have recently backed up a Blu-Ray disc of mine to my PC. In that Blu-Ray there are unnecessary audio tracks and subtitle tracks(to me) and I wish to take them off the Blu-Ray Disc,leaving the one's I want.
How is that possible?

MakeMKV or ClownBD and make a single mkv or ts file?

Or do you want to keep the menus? Maybe clown_bd bd copier.

I want to keep the menus and the extras. I just want to strip a few audio and subtitle tracks off it. I don't want to make it an mkv or anything. I want it's format to stay as it is,so I can burn it on a BD blank disc

Can't BD rebuilder do that without any shrinking?

and if I want to make an mkv file out of it I can use MakeMKV...although there is a problem with that. MakeMKV takes only index.bdmv or Movieobject.bdmv and gives in the end of the process multiple mkv files,each one for a bd chapter. How is it possible to extract the whole movie into one and only mkv video file? Is there some sort of configuration or do I have to use another program to do that?
Thanks for your fast replies

I normally use RipBot for BD>MKV conversions. But you can use tsMuxeR and select just the main movie and desired audio, mux that out, then you may be able to use that file for MakeMKV. Don't know about subs as I don't use them. There is also a little program called BDInfo that can give you the .mpls playlist of the main movie. This comes in handy some times as some BDs split the main movie among several .m2ts files.

hmmm tsMuxer.... but I am interested in leaving a few subtitle options on...
I got BDInfo although I think MakeMKV doesn't take up .mpls files.
I tried BD Rebuilder but it's kinda hard to figure out how to make it work without shrinking the BD. I can only put the destination to be up to BD25 but if the primary blu ray disc was a BD50 the program will certainly re-encode everything and I don't want that.
I just want to take off Audio and subtitle tracks and I don't mind if the disc's size doesn't get reduced much. What I do mind is the video quality since I want it to be left intact. I don't mind using shareware programs as long as they do what I want
