Ben -- is that H.264? It seem "mpeg 4" is not well defined. from Wikipedia:

"MPEG-4 is still an evolving standard and is divided into a number of
parts. Companies promoting MPEG-4 compatibility do not always clearly state
which "part" level compatibility they are referring to."

That's because PPT punts to the "system" for decoding -- it has little if
any built-in support. A freakin' nightmare.

I think H.264 is getting better and better supported.

Question: how is MPL planning to support it? Is there a
not-too-hard-to-install cross platform lib???
