Can you please comment on why you think these bugs make kino unsuitable
for release; specifically, which section of policy is violated? I'm not
denying that the bugs you reported are nasty and should be fixed, but
unless you convince me otherwise, the severity looks inappropriate to
me.

This sounds a lot like an old Xv bug that first came up in 2002. Can you
please supply me with the output of xvinfo? Which system are you testing
this on, and what's your graphics adapter? Is DRI turned on, and does it
make a difference if you turn it off? For reference, the original
discussion should be available from here:

The audio problems seem to be caused (at least) by big-endian length
fields in an otherwise little-endian WAV file. I'm not too familiar with
the various video encodings. I'll have another close look on it over the
week-end, but might have to pass on the problem to upstream for a fix.

Thanks,

Daniel.
