Nepatīk lasīt tur, lasi te:
http://mpc-hc.sourceforge.net/media-player-features.html
It has built-in codecs for MPEG-2 video and codecs for LPCM, MP2, AC3 and DTS audio, and also contains an improved MPEG splitter that supports playback of VCDs and SVCDs using its VCD/SVCD/XCD Reader. 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.

Supported Video, Audio and Image File Formats:
WAV, WMA, MP3, OGG, SND, AU, AIF, AIFC, AIFF, MIDI, MPEG, MPG, MP2, VOB, AC3, DTS, ASX, M3U, PLS, WAX, ASF, WM, WMA, WMV, AVI, CDA, JPEG, JPG, GIF, PNG, BMP, D2V, MP4, SWF, MOV, QT, FLV"

Katrā ziņā tas arī praktiski ir rādijis un atskaņojis to, ar ko WMP ir problēmas.
Jā - tas gan ir jau drusku cits projekts - Media Player Classic Home Cinema.
