"Edit: The unaligned pitch seems only to occure on the
chroma planes, but to make optimal use of SSE2/SSE3 the
pitch of these planes should also be a multiple of 16."

IanB, could you look at that?

    The latest release is trialing priority alignment for chroma in
    planar format. Thus requesting a 16 aligned frame will return a
    frame with chroma 16 aligned and luma double this (32
    aligned).

    So far DGDecode has come unstuck with invalid code
    assumptions and other may follow. We can alway back the
    change out if to many things bite.
