What equipment (video tape, Ultimate TV, etc.) is required to record an HDTV broadcast at 1080i? If they can be recorded for later viewing at that resolution what is the cost of the media that has the capability to record it? I guess that if it's Ultimate TV then the hard drive is the media which is obviously almost infinitely reusable. Are some of these transmissions in conjunction with the tuners that receive these signals carrying some type of copy protection encoding that would prevent them from being recorded?
