Play avi files in DVD player with DIVX features

I have avi file with its SRT file. When I play in Window Media Player (WMP), the subtitles looks the bottom middle.
However, when I play that avi & SRT file in my DVD player, the subtitles looks smaller in the bottom left side.
Anybody knows how to display the subtile in DVD player as good as in WMPl? :confused:

Check your manual of your dvd player if you can change the font size.
