Hi,

I was the one who was initially having problem with this. I tried
without gnome-mplayer, and -cache does not work very well: -cache 8192
will cause nothing to be played.
I tried limiting the DVD speed too, but it still did not prevent the
videos from being jerky.
The machine most certainly has more than enough computing power to
decode the stream, and totem plays it very smoothly. Is there anything
else I could try? I like mplayer more due to the vdpau support. Here is
the console output:

$ mplayer -dvd-speed 2 -vo vdpau -mouse-movements dvdnav://
