MKV to DVD is giving me troubles with the subs

I usually get my anime straight from bakabt, and it's always with softsubs , .ass subs to be specific and .mkv format, i found the program to be quite to my liking, due to how i could render menus exactly how i liked them, however i am having a slight issue, the subs for some reason are thrown out of tempo by the program and are not rendered properly, i havent found a way of fixing this, any ideas of why is this happening or how can i fix it?, thanks in advance

Whoever wrote your siggy needs to learn how to spell. The word is might, not migth.

It's written in dwarven, unless you are in a specific state of mind it's incomprehensible to people, and what does it has to with the issue i was having? that i wound up fixing anyway
