The only way to get a video feed like that is a hard modification of the console itself, inserting a card containing a USB port into the circuits of the display.
There is no way to 'plug something in' to the DSi to do this, none of the DSi's other ports have any link to the visual feed.
no you can't play dsi games in ds but you can play ds games in dsi.
The DSi can play DS and DSi games, as well as DSi ware games. It cannot play GameBoy games or 3DS games.
There are only a tiny handful of 'DSi games', games which specifically need the DSi's camera to play. Most are even DSiware. So technically all DS game cards will work just fine on a DSi, there's no need to do anything to get them working.
Yes, you can play DS lite games on the DSi as well as the DSi XL
A US DSi can play UK games
