You're not wrong -- I could use -vo sdl to get video without
tearing with Composite enabled, but mplayer's startup and
shutdown delay became unbearable (displaying a black screen for
over a second on both startup and shutdown, as if the system was
changing resolutions or something). I also tried -vo x11 (which
is really slow since it needs software scaling to go fullscreen),
but the x11 driver always has tearing problems, regardless of
the Composite setting.
Which output drivers are you using, btw? Nvidia's drivers
implement the xv accelerated video output, so it sounds a little
strange when you refer to xv as if it were in opposition to using
Nvidia's drivers. :-)
