Different hardware, for which no open-source driver code exists,
AFAIK.  The CLE266 MPEG decoder does MPEG-2; the later chips also have
H.264 acceleration and are therefore different and need different
drivers.

That's not the issue.

The later chips do still have support for YV12 but not directly in the
overlay layer.  Instead there's a video blitter that does the
conversion.  We've no support for that in DirectFB at the moment (but
I don't think it would be hugely complicated to add if someone has the
time).
