CoreAVC is a Video software by CoreCodec. The software is a codec for doing playback with multimedia files and decoding Blu-ray and DVD movies. It is a specialized tool for supporting special media formats such as H.264 that requires a codec to decode it when H.264 is being streamed. It seems windows media player is smart enough to automatically change codecs for those files, but MPC-HC isnt. I mention coreAVC early on it just doesnt get hardware accel on ATI. On my media PC, FFDSHOW cant do 1080P smoothly, while CoreAVC can - (60-80% CPU) whereas 7's built in codec (on properly encoded files) gets that to.
