How to convert BD or DVD to mkv with subtitle selection

[vhwul62]

On disk I have:
- Original Blu Ray
- DVD (VIDEO_TS) .vob files
- .TS files (TV-recordings), often also 7-9 GB

These files can be played back by VLC nicely, of course.

Would like to convert them to high quality .mkv files, but, similar to the originals, with subtitle(s) selection (BD/DVD)

Tried TMPGEnc Video Mastering (latest version): it reduces the size to only 10% of the original (BD 24GB results in 2.5GB MKV)
Tried MediaEspresso v7, same BD is now 8GB MP4 - AFAIK MediaEspresso does not support .MKV
(Note: did nót use 'high quality'in MediaEspresso's, but rather its default 'Faster Conversion").

Both files (.MKV/MP4) could be played in VLC.

However..,
in both cases, when playing the file, I cannot select a subtitle, i.e. VLC Subtitle selection is 'greyed out'.

Some [Newbie!] questions..
a) I am not sure which one is better, quality-wise, .mkv or .mp4 (I would assume: larger files->better quality?)
b) Alternative tools for conversion to .MKV, for above listed files (BD/DVD/.ts) -noticed RipBot264 and VidCoder
c) will these toolsy support subtitle selection when fils are played back?

I haven't tried them out yet. first would like some expert advice on this.

Thanks!

LATER:
tried VidCoder - seems to work!
Main Window: Subtitles [Edit] a language can be added - lateron when playing the video, language can be selected
When set quality to high - [Settings->Video: Slider totally to the left, Constant Quality '0'] the 24GB BD results in a 13.7GB file.
