Jan,
This HDMI adapter does offer a "back-door" type of access to the cable and
satellite content which could otherwise be difficult or impossible to gain
access to / extract in mpeg2/mpeg4/H.264 .ps or .ts streams given the way
the content cartel works and cable/satellite hardware is designed.
Recompression from the HDMI capture down to a BluRay or HD DVD compliant
format would be inefficient and risk artifacts and image quality loss, but
may be the only way to capture and then economically archive this type of
programming. Alternately, perhaps the cable and satellite providers will
offer burners in their HD PVRs. Time will tell.
Since a 1 TB drive has already been announced, holding ~90 minutes of this
raw content, I would think the time is almost immediate when a very usable
somewhat modestly priced NLE could be built. Blackmagic identifies Adobe
Premiere Pro, Final Cut, and other software as already being up to the task.
Looks like a new and interesting next frontier.
