What use would it have to implement MPC-HC subtitle engine if you don't implement the MPC-HC codec's
HW acceleration works for example with Cyberlink's H.264 codec. So it is not requiring MPC-HC codec. Also we don't want to start to distribute h.264 codec as it most likely has some licensing fees that we would be required to pay on downloaded MP basis (most likely MPV MPEG2 codec is already on that same gray area ).
