Just installed svn version of mythtv and I am eager to try out subtitles. When I go to
playback and select menu->subtitles->Finnish, mythtv just Subtitle track 1, no text shows
up . What could be wrong here ?
Someone mentioned about enabling them. Do I need to do something else to display the text ?
I did not find anyt keyboard command for that from mythtv.org

The current DVB subtitle code makes no attempt to scale the subtitle images
which are scaled and positioned to be correct at a video size of 720x576.
Some channels like E4 typically use a video resolution of 544x576 so when the
subtitle images are passed to the OSD for display the wrong position and image
size is given for the video resolution being used.
Could you try the attached patch and report back.
I'd be interested to know if DVB in NTSC land uses subtitles and if so are you seeing
similar problems with the subtitles displaying in the wrong position or partly of the screen.
Thanks, Paul
