Well this is going to be my next little upgrade to the ATV,
So I will be removing the wifi card and replacing it with the Broadcom Cyrstal HD card, Through XBMC I will beable to play full 1080p HD video.
And since I already have ATV Flash, there no need for all the SSH and terminal hacking.
So I jumped onto eBay Australia, as I could not find a stockest in NZ, found what I was looking for and its now on its way over to me.
Should be a good little hack project.
