I am pretty sure it isn't just a scheme since you need a different kind of tuner in order to record true HDTV, Atlantic Scientific (one of the biggest cable box vendors) just released an HDTV version of their DVR, and don't sell these boxes directly to the consumer, so not sure what they would gain by setting up such an advertising scheme.zack said:Are regular Tivos and ReplayTV capable of recording HDTV.. in both 4:3 and 16:9 aspect that is? I've seen DirecTV advertise that you need their own HD-DVR box to for it to record HD aspect ratios properly. It's probably just an advertising scheme, but just wondering.
