A *.mp4 and MPEG-4 Timed Text support added. An AAC decoding filter makes MPC suitable for AAC playback in MP4.
MPC Home Cinema also has H.264 and VC-1 with DXVA support, DivX, Xvid, and Flash Video formats is available in MPC HC. MPC can also use the QuickTime and the RealPlayer architectures. Media Player Classic supports native playback of OGM and Matroska container formats.

Media Player Classic Home Cinema allows you to enhance, decode and accelerate a broad span of movie formats like x.264 with GPU assisted acceleration and image quality enhancing. The WMP Classic Home Cinema player does not require many system resources than the rest of the video media players to run smoothly. This is a low PC resources windows media player that runs on slower machines with older CPUs.
Modern graphics card offer the possibility to decode partially or completely a video stream using DirectX Video Acceleration (DXVA), in order to reduce CPU usage dramatically. MPC-HC includes an embedded video decoder that uses this technology, to decode x.264, H.264 and VC-1 with hardly any CPU time required.

MPC Homecinema is available in 64 bits version for Windows Vista and Windows 7 (it should also work perfectly on Windows XP 64bit). Some functions have been removed, because they are not available in 64 bits yet: internal MPEG decoder and QuickTime are not supported, some “tricks” may not work because Microsoft Detour library is not available free for the 64 bits platform.

32 and 64 bits are completely separate world : MPC-HC 64 will use only 64 bits codecs installed on your machine. It’s not possible to mix in one process 32 bits Dll with 64 bits, so you will still MPC-32 to play RealMedia or Quicktime for example.
