Hardsubs are subs which are hard-coded into AVI video containers. You also can say that the hardsubs are part of the video itself. You cannot switch between languages and for watching them only a player with the codec for playing the video is needed.
Softsubs are simply files (ass, ssa, srt, txt) whose format depends on the exact subtitle encoding software to be used to interpret these. Softsubs are not part of the video like hardsubs. The MKV container makes it possible to put as many subtitle formats into it as you want and after the encoding stuff is done you can switch between the subtitle files you have inserted. To play Softsubs you need the vsfilter, the codec for mkvs and Media Player Classic.
Only SOME advantages!
Programs which are needed: vsfilter, the player which is needed is Media Player Classic (in most cases this player is already installed in the directory c:\programs\windowsmediaplayer). Videolan (VLC media player) DOESN'T suppor softsubs. And last but not least the thing which gets ignored very much: you need the CODEC. I know that a lot of people are complaining that their computer cannot play certain audio or video formats. Guys your computer can only do what you are teaching him. I won't answer on any question concerning the video doesn't play. It's your job to check which codecs you have I don't have any list laying around here where stands which codecs you miss or which you have... I only want to say that my way of helping you when something isn't working is very narrowed ....when such problems appear it is for 99,9% a codec problem...

for vobsub and vsfilter: http://www.divx-digest.com/
software/vobsub.html

for codec packs: http://www.filehippo.com/
download_klite_codec_pack/?1794

(as I said I cannot tell you which codec pack you need since I dunno what codecs you have and which you don't have. For ones without any advanced codecs i would say version 2.71 is good but I wouldn't lay my fingers into the fire) in most cases media player classic is already included in the codec packs!!!!

When you have everything which is required now we go to install everything:

(Install the codec first when you haven't this one... )

Install vsfilter, if you cannot open it via right-click and release... copy the file (*.dll) into following directory c:\windows\system32. please take the filter from the site i have given you. (scroll down for the ones who not find it) you have two folders in the archive. copy the UNICODE filter! After you have copied the filter
go on start --> run. enter this into the box regsvr32 VSfilter.dll. Click OK then. After you have mastered the step and everything worked fine a window should pop up that VSfilter.dll is running!

When you have everything done properly you should be able to watch the mkvs on mediaplayerclassic! another point is that a green arrow should appear when opening a file with softsubs...

IMPORTANT: Only because you were able to play subbed anime files it doesn't have to mean you have vobsub or you would be able to play softsubs. ANIME WITH SUBS ARE VERY OFTEN HARDSUBS AND THIS DOESN'T REQUIRE ANY EXTRA PROGRAMS --> ONLY A PLAYER IS NEEDED!!! SEREI NO MORBITO IS ALSO HARDSUBBED...

when media player cassic also says that you are not able to play the file but you are able to play it on VLC player... it doesn't mean very much since always certain format codecs are integrated in the player. Therefore VLC player isn't able to recognize/ show the subtitles in a good quality. the later versions of media player classic should be able to play mkvs without installing any extra codec. Media player was developed by GABEST...it's the same developer who is responsible for vobsub so it doesn't irritade why it can recognize media player classic and its actions. VLC Player has only a good point for me because it can play incomplete torrent files...nothing more
