i'm new in here so this is my first post - but somewhere gotta be my first

i too is deaf and i got a dvd player that supports divx movies, and by trial and error i figured out how to show it with subtitles (although the font is a bit small, i havent figured out that part yet (but i got some ideas to try out, will tell if they works out, just need some time off work lol)
Also, I see this question has not been quite answered yet, but also, better late than never.
I am assuming you got files and you got subtitle files in .srt format.
To make it work, you got to work a bit. If the file name of the movie is long, you got to shorten it down. If it is episodes of some tv show, you gotta make the episode number visible on the dvd menu (it cuts it off so the dvd player will believe it is the same thing all way thru, and use the first subtitles on all of the episodes)
The second thing is, the movie file name and the subtitle file name have to be exact the same (but of course keep the file endings .avi and .srt. I use to simply copy the movie name and paste it in the subtitle name so they will match exactly. They also have to be within the same folder or on root directory of the dvd. If you burn the dvd with movies in one folder and srt in another folder, it will not work.
Got it?
1 - Shorten file name
2 - Exact match of file name of both movie and srt.
Hope this works for you too!
Good luck!!
