DVR capability - requires a built-in tuner as well
I've been thinking about this one. For the aTV to serve as a DVR, it doesn't necessarily need to have a tuner. In fact, having a tuner will basically be a waste for satellite users and digital cable users (assuming that the aTV wouldn't have CableCard).
The argument can be made that all the aTV would need to be a capable DVR would be component inputs, an IR blaster, and great software. The users own cable/sat box would serve as the tuner. The aTV software could handle the scheduling duties and send out a signal via the IR blaster to activate the cable/sat box.
To do all of this, the aTV would need a good analog to digital converter, preferably some sort of h264 encoding chip.
With all this said, I suspect this would be extremely unlikely to ever happen.

TV had a tuner, many people wouldn't need or want cable or satellite. Why pay a monthly subscription for the major networks when all you need is a TV tuner? don't forget in the US, the DTV switch is right around the corner and lots of people can get HD free over-the-air. Plus, most cable and satellite boxes already have built in DVRs.
