This is NOT
possible. There is FAR too much data in an analog HDTV stream and there are no consumer products that can do this AND still sync in the audio stream.
It is either firewire tricks or full support via CableCARD (Or something like it) or nothing. If you were to leave your providor, the only way to get HD content would be with an OTA capable HD tuner card and unless you are in the GTA, there is very little available this way.
