Mp4 Playback... Does K-lite Do It?

i tried searching but, whee, mp4 is less than the minimum search limit.

does the codec pack install the 3ivx MP4 demuxer? it sure would be nice to also have it in a small install (less than 2mb) along with ffdshow or something, so i can pack along the decoder/demuxer with slightly undersized dvdrips/scene releases...

3ivx doesn't fully support MP4.

But there will be full MP4 support in the next version of the codec packs.
