I tried  -framedrop. It gets a little better

I have Xvesa, 800x600, 16 colors. Video quality (each frame) is good.

My video card is ISA, a Trident with 1mb.
My Pc has 4 empty PCI slots, but no AGP.
The other 2 video cards available are just 512kb.

I'll try these settings and make that search..

I tried   mplayer -autosync 2400  -vo sdl vcd://avseq01.dat
(autosync recommended factor is 30).
This gives me no sound at all but the video goes fair - a little slow, I
suppose.

When set to zero,  sound and video interfere greatly on each other.
-vo sdl   works better than   -vo x11
I also tried  -quiet   which stops the verbosis but then I noticed no
difference.
