my old 400Mhz celeron was not enough for xine-plugin, and mplayer is a
primer no solution (de-interlace was allways disabled anyways).
a 2200+ AMD is totaly blocked when decodig HDTV, yes i DID test that with
the astra test sigal, it was nice, but there are years to come until that is
needed.

well it's no i386, and you know that, and having a sw demultiplexer is not
all what we need, it is just data moving.
b.t.w. replay does not work, so out-> yes, in -> no (some stuff works, but
most boxes are to weak to shuffel the data fas enough)
