Re: dvbd

Hi Michael

Thanks for your reply. Tweaking the scheduling is ususally easy to fix. 
I might want to look at the buffering too. It ought to be a system thing.
I never got VDR working properly, and currently I use mplayer/mencoder 
to record.

But one thing which I would like to do is to use dvbd together with VLC, 
because VLC can handle the DVB subtitles used in Denmark. But VLC does 
not seem to like connecting to the dvbd socket. If anyone have success 
with that, I sure would like to know.

Also at some time soon I would need to stream some DVB signals. But I do 
not like the way this is done by most tools, they seems to be using up 
CPU cycles even if nobody is listening.

  Regards Kjeld
