I have the Atv2 jailbroken and working.
Up to resently it hasnt been an issue, but yesterday i had to modify my network with OpenDNS because of the kids, block some sertain web pages.
Every device works even the Apple tv. But when I try to access files on my server thorugh the apple tv mediaplayer i cant find it. When I try to add share i only find th AFP devices such as the mac in my network. But i really need to find the SMB devices because its on the microsoft platform i run the server. It just keeps serching and searching for new device for hours nothing happes.
And as soon i go in to my router and removes the primary and secondary DNS adress for the OpenDNS everything works like a charm again. I really need this to work. And I also need to block some websites from the kids using open DNS also.
