That is by design that way. MPEG 1/2 was designed to need low computing
power for playback. Because the DVD-Player and other devices should not
need a very complex CPU which is rather expensive. A not that complex
CPU produces less heat so you do not need active (FAN) cooling, which
makes the video playback equipment silent, and the fan is one thing
which is very likeley to fail after a few years. Which means less defect
devices the companys have to worry about. And more happy customers.

MJPEG was "designed" do be a format that does not need to "much"
computing power do be compressed in realtime. And to be rather small.
One onther very important thing is that mjpeg was also designed to be
very easy editable (MPEG ist not really editable). 

Two differnet requirements, two differnet formats, and in genaeral a
good solution for each purpose.

You should be able to watch what comes into the card at the same time on
the output of the card even when recording. At least it works on the
BUZ/DC10/LML33 cards. 
You cannot record and view a differnet stream on one card. 


auf hoffentlich bald,
