[vdr] DVD subtitles - exprimental patch, need help

[Andreas Schultz <aschultz@cs.uni-magdeburg.de>]

Hi all,

I have hacked together some subtitles support for DVD's. It basicly 
works, but i have some problems with video distortions.

I use a 2Bpp OSD to display the subtitles. Mostly, this works smoothly, 
but every 5th or so subtitle causes the video to flicker and sometimes 
stalls the video for a short moment.

Could somebody out there have a quick look at it, maybe i'm doing 
somthing stupid with the OSD, or is there a know problem with OSD 
causing video problems even with low bpp OSD's?

The patch is at
