The 770e (266Mhz) had the video decoder card, the 770z and 600e (366Mhz)
did not.

Wild conjecture:  low-end machines playing DVDs are probably doing the
decode
in hardware, not software.  The hardware in turn probably paints directly
to
the video RAM, which in turn is not rendered to the S-out port, because it
wasn't generated the normal way, and thus isn't captured by the VGA->video
translator.

Caveat:  I made all that up on a hunch, but it does seem to fit the (megre)
facts at hand.  I should RTFM, but this is recreation for me, not work.
