Alright, here's the catch. Matroska (MKV) is just a container.
Anything can be put in it. Think of MKV, AVI, MOV, etc. like boxes.
DivX, MPEG-4, H.264 and XviD are all compression formats, like
folding or pressing the air out of a bag and sealing it. You can put
any of those compressed things in the box. Now, your run-of-the-mill
MKV file contains XviD, DivX or MPEG-4 data (they're all essentially
the same thing with minor differences). DivX players will play those
files back. Recently, however, a new video codec (compressor) called
H.264 has been developed, which packs higher quality video, which
DivX players CANNOT read it.
In order to get your DivX player to work with these videos, you'll
have to convert it, which will take time to do, and you'll lose some
quality. For Windows (you haven't said what you're using, but I'm
going to assume Windows) Gordian Knot or VitrualDub should be able to
convert it (assuming you can play these H.264 videos on your computer).
An alternative is to try and get a different player. There are some
set-top boxes that can play back H.264, but they often don't come as
DVD players, and usually either play off of a network connection or
from a flash memory card. These usually don't play MKV files, and
will usually require your files to be in MP4 containers. Now, the
most flexible way to play back MKV files on your TV, in my opinion,
is the use of a hacked XBox running XBMC. Not quite sure what the
availability of XBoxes is like there in Argentina, but if you're
technically minded, it's worth a try.
