Should be fast enough. (I have an AMD k6-2 350MHz) But top says 50% on
your machine. Is the processor idle for the other 50%? Or are you running
other demanding tasks (probably not, but I must ask, because I do not
understand why the kernel doesn't give more cpu time to mplayer).

Mmm, this works as it should.

I'm puzzled; some suggestions to try to find the source of the problem..

1. Try to run mplayer at a higher priority (As root: nice --20 mplayer \
-vo zr blah.avi) and see if it makes any difference.

2. Alternatively you can try my dummy vo_zr.c
(http://cube.dyndns.org/vo_zr.c) that does not play images on the tv
screen, but only performs the internal jpeg compression, if there are no
problems on your PCI bus, this change should not change playback speed by
a noticable amount.

3. Maybe try a kernel without SMP support (should not make a difference)

Let me know if you find something.

Greetings,

Rik.
