Windows 7 Codec Support

In addition to the codecs supported by previous versions, Windows 7 supports an impressive list of new codecs and media containers out of the box.

New containers:

1. MP4
2. MOV
3. 3GP
4. AVCHD
5. ADTS
6. M4A
7. WTV (new Windows Media based format for PVR based recordings)

New codecs:

1. H.264
2. MPEG4-SP
3. DivX
4. Xvid
5. MJPEG
6. DV
7. AAC-LC (regular AAC)
8. LPCM
9. AAC-HE

You can get all these codecs and more with the K-Lite Codec Pack, however, this is the 32-bit version. The 64-bit version of K-Lite doesn't offer many codecs at all.

Now, if Microsoft can just add support for the Matroska file format, we'll be all set.
