Hello all,

I enabled drm. That works fine now. Within xine recordings play
smoothly with about 38-40% CPU load, where earlier, this would go to
90%

However, within mythtv recordings play slightly too fast. Live-tv too,
but there it also starts stuttering, probably because the buffer runs
dry.  What can be the cause of this? I have my recording profiles on
720x576. So that cant be the cause.

Suggestions are welcome

Bert

Only two things are infinite:
human stupidity and the universe,
and I'm not sure about the latter.
