the EXAVSync option has nothing to due with Xv.  The Xv anti-tearing
stuff is handled separately by an Xv attribute and is enabled by
default.  The EXAVSync option stalls all EXA rendering until the
display is past the relevant vlines.  In most cases you shouldn't need
the EXAVSync option for videos.
