New video comes out which shows us playing AVI/RMVB on DS

Last time, there was a youtube video which showed us something plays RMVB directly. Now, new video comes out. The new video shows us more interface views on the bottom screen, and according the interface, surely it is not moonshell. You should also go to see it through the link below:

According GBATEMP's claim, it is some kind of slot1 hardware, as you can see below:

"I've just been confirmed by a reliable source (who wishes to remain anonymous) that this is not a hoax and is currently a WIP. It is a new slot1 card that will be announced shortly! Unfortunately we're not able to divulge any more information! But we'll remain sceptical until we have the product in our hands to test for ourselves."
