	Todd and Paul are. Paul's tests seem to indicate
some strange problem in the MMX function itself? See:

	Mino, you mentioned some sort of harness that you used
to test the MMX code. If it is standalone, could you please
send me a copy?

	Otherwise, is there any chance of getting you to check
for buffer overruns in the function? Having some dummy data
(say a few hundred bytes of 0xF00F0FF0) either side of both
the source and destination buffers should be enough to show
any errant writes.

	And if any of you could provide -v playback output that
shows the problem, it may help us.
