Just ran across this little gem: Perian, an open-source QuickTime codec for a few of those other formats that QT chokes on.

Perian enables QuickTime® application support for additional media types including:

• AVI and FLV
• 3ivX, DivX, Flash Screen Video, MS-MPEG4, Sorenson H.263, Truemotion VP6, and Xvid
• AVI support for: AAC, AC3 Audio using A52Codec, H.264, MPEG4, and VBR MP3

Woot.
