Daewoo DV-115

Hi all.
More than one year ago i purchased this home theater system
now that i get more involved in dvd’s i’d like to know if anyone
here knows what kind of player is inside
Since from the manual it was not supposed to play dvd±r and/or
svcd while it does i was wondering of what kind of hardware is,
and then if it’s “hackable” in some way
I already know there’s a region free one, but i was thinking about
better compatibility with media
