I remember one of the first Sharp HDTV manuals gave instructions for recording to a Blu-ray recorder through firewire. That was in 2005!
So here we are in 2014 and still no Blu-ray HDTV recorders in the US market. Recording to a DVR then offloading to a computer using a Hauppauge HDPVR and then authoring a Blu-Ray or AVCHD disk just takes too much time to be practical. Surely someone can just put this all into one device and record through component.
