All are MMC booted.....................umm, you going to ask me how about internal flash boot? have not tried yet, will post later...
Might be worth trying. Having system on mmc can sometimes cause audoi stuttering. At least with stock media player or internet radio applet, not sure about mplayer. The problem is that since 2.6.18 kernel, mmcqd kernel thread has higher priority than audio daemon so with random mmc writing audio may stutter. If you hear this try to run
Code:
renice 0 `pidof mmcqd`
as root to check if it goes away. Good place to run it is somewhere inside /usr/sbin/osso-mmc-mount.sh script which is run after mmc card is inserted. I have mentioned this few times but nobody ever complains about it so maybe it happens just to me :-)

As for 770 being better in smooth playback, maybe kernel preemption helps too. N8x0 kernel is not preemptible so latency in kernel may be higher.
