Finally, I found something. It's Dolphin!
I've done some longer testing, always playing the same video parallel
with a dd if=/dev/zero of=/tmp/10G bs=1M count=10000, in mplayer, for a
minute, several times. When I do this by opening the file in Dolphin, I
get about 15 interruptions, some for longer than a second. Started on the
command line, there are very few, I can play the video for minutes
without a gap. Hooray!
In KDE, I usually play videos by opening them in Dolphin. I exchanged
'mplayer %U' by 'xterm -T MPLAYER -e mplayer %U' in the settings, now
mplayer runs in a terminal, and all is fine. I created a window rule so
the terminal automatically minimizes. Cool!
It only happens in mplayer and mplayer2. Other players work fine, but I
like mplayer best, and prefer to run it without any window decoration.
Now, would this be an MPlayer problem, or one of Dolphin?
