This is definitely something you can do. It's as simple as plugging the dvr into the input for the dvd recorder and hitting play on the DVR. Sadly, you cannot do this "quickly" recording an hour long show will take an hour. You can write to blu-rays, but you'd need a blu-ray writer to do so. As for transferring the files to PC, it can be done, but requires a little bit of DVR hacking, and PC installation. Definitely not something for the faint of heart.
