Improving Internal Table Saw Dust Collection

[Pillguy]

Hi All,
I made a video of the sawdust flow in my table saw, with the goal of improving dust collection within the saw. I did this with a clamp, camera phone and a camping headlamp. Took about minute to set up.
I am getting too much dust out of the top of the saw (no overhead collection as of yet) and think there can be some improvements within the saw.
I am thinking a bit of a wider internal cover and possibly moving the hose to a flexible internal position.
Has anyone done this, thoughts?

not sure whats going on there. the red part is the blade and the black part in bottom is the motor.
i would put a scroud around the blade so the dust is contained and sucked away.
have you a pic of the underside  of the saw.

on my saw.
i put a ply bottom on the saw. i built a 4"box across the bottom where the dc port is . there is a slot on the top of the box. i built sides above the slot to form a funnel  into the slot.
the box has a sloped bottom as it gets farther awy from the dc port.
i removed all the hose and covers from the trunion assembly. this allows all the dust to fall into the slot. it works a treat . i have overhead guard as well.
i found that before i removed the covers and pipes that the squashes 4" pipe got blocked regularly adn the dust built up. the blade then threw it all back up then.

if you want pics i can get some
