First, in my opinion they should all be legal, including Aereo. That said: what you describe sounds legal, but it wouldn't work technically unless you have amazing upstream Internet bandwidth. The average AppleTV customer does not have high enough upstream bandwidth to record an OTA (or clear QAM) HD (1080i) MPEG 2 transport stream. There is just no way. Never mind multiple streams if there are more than one tuner in action.
So, the recording itself would have to happen in the cloud, and we are right back in Aereo territory.
(For anyone asking "what about Slingbox" - the video stream gets transcoded and recompressed to within an inch of its life for it to work. Basically the video quality gets killed dead. Not a big deal if you want to catch with something on your phone on the go -- but not how you want to watch on you large HDTV at home).
