Correct. The CLE266 only does hardware MPEG2 decoding. The CN400 does 
hardware MPEG2 decoding and hardware MPEG4 *acceleration*. And I would 
agree that doing software MPEG4 on an M6000 is probably wishful thinking 
;-)

As an aside, everything I'm being told seems to indicate late Q1 for 
CN400 based board (Nano-ITX, VIA SP) :-(
