I can only test my system (core2-duo 2.1 running linux 2.6.21-smp).
Benchmark run with this command on a ISO image on my HD in order to
minimize the impact of slow DVDs and disk I/O:

for i in 1 2 3 4 5 ; do time ~/mp7/mplayer -dvd-device DVD.ISO 
-really-quiet dvd://1 -dumpstream -dumpfile /dev/null ; done >& 
external.log

(the title in question is a 2GB file)

Although sometimes the external dvdread is marginally slower it fixes 
the problem; IMO we should upgrade our buggy dvdread ASAP
