[Mplayer-dvb] cpu (system) load with dvb-card at 100%

[bln_77]

hello everyone,

first i want say that mplayer is really a great video player. i use
with my dvb to watch video on my tv and it works great. but i also
have al tiny little problem...
the cpu load (system) on my computer (p4 with 2.4 GHz) is mostly at
100%. when i give mplayer more priority to avoid stocking of playing
from others running tasks the whole system nearly freeze.
under top i can see that mplayer is consuming the cpu power.

i played a normal avi file with mp3 audio over my soundblaster live
with spdif out (alsa9). if i play with the -nosound option mplayer
only take 25% cpu power but when i play the same file on my X windows
WITH sound, mplayer even take only 30% - 40 %. so i think that the
sound is not the problem. i also tried mplayer (a older version, i
think it was 0.9pre8) on a other computer with the same sound and dvb
card and its the same problem!
have anyone an idea, please?
thx
thomas
