Yeah, I'm not convinced you want to drive the media from the tab anyway. I think the current best bet (as long as you can suffer another device) is something like this: http://drivecase.stores.yahoo.net/mestcgdiusb2.html (only smaller).

This is a media player that has host mode usb, so it will take a usb storage device, and play any media that is on it out of a TV. So you plug the n8x0 into it, and it simply acts as storage. Then use the onscreen menu to play the media.

It is too big, but I have seen smaller options - the other angle would be to get a hdd media player that had host mode usb. So it has its own storage, but also can accept an external usb storage device. And then this could also act as extended storage for the n810 for whatever (rainbow tables )

Obviously this isn't the same as tv-out, for presentations or using the n810 as a desktop with screen and keyboard, but that isn't what this thread was getting at - at least initially.
