I found another set of videos of the same lectures at
http://www.archive.org/details/arsdigita_05_algorithms ("video files"
link on the left). These do play with MPlayer (latest SVN), but the
video gets scrambled (the sound is unaffected) at about 0:39, with
MPlayer generating the following errors:

[rv20 @ 0x6a1f10]ERROR at MB 19 14-0.086 584/584  1%  9%  0.3% 0 0

Movie-Aspect is 1.33:1 - prescaling to correct movie aspect.

[rv20 @ 0x6a1f10]HEADER ERROR ct: -0.085 588/588  1%  9%  0.3% 0 0
... and so on

Before that, the video plays fine (though a bit jerky when compared to
RealPlayer), only generating a bunch of "[rv20 @ 0x6a1f10]unknown bit3
set" errors.

I'll include what's printed up to the first error (the rest is just
"unknown bit3 set" errors and the HEADER ERROR errors):
