I just upgraded to rc5 and using "mmap:noblock" have fixed my desync
problem. Thanks.
I also get this message only when seeking (only with mmap:noblock):
alsa-space: xrun of at least 3.896 msecs. resetting stream  0.0% 0 0 18%
It is harmless (sound is ok, sync is ok).

Hm, you are right. ogmtools are all I need. I didn't read TFM carefully :(

Is here anybody using ogm container ? I need some help with subtitles.

I put .srt subtitle in ogm container with video and audio stream (subtitle
is in cp1250 codepage).  Mplayer doesn't show some characters (I suppose it
treats them as latin2).
-subcp latin2|cp1250 doesn't help (but it works correctly if I use subtitle
from separate file).  My fonts are generated with:
./subfont --unicode --blur 2 --outline 1.5 iso-8859-2 24 arial.ttf

I suppose if subtitles are put in ogm container, mplayer treats them
differently and -subcp is ignored ? Is this some ogm restriction or is it
simply not implemented ?
