I don't think your sound driver or audio hardware is to
blame. The fact that the problem depends on the size of
the window indicates that it is probably related to the
2D video acceleration, i.e. hardware scaler. I suspect
that you're using software scaling.
Please install the "xvinfo" tool from ports or packages.
It displays the status of the XVideo extension. The
output should look like this for hardware acceleration:
X-Video Extension version 2.2
screen #0
Adaptor #0: "Radeon Textured Video"
Of course the string ("Radeon") may vary, depending on
your graphics hardware. If you get an error message or
a string indicating software rendering, then that's
causing your video playback problem. In that case you
should check your Xorg configuration and maybe update
your Xorg video drivers.
Best regards
Oliver
