Copying Video Content off of a DVR


I hope this is the right forum to pose this question. If not, please re-direct me.

Anyway, I subscribe to a cable service which provides me with a DVR built into the cable box.

Up until now, if I want to archive any movies or sporting events, I would have to use a DVD recorder to record it onto a DVD-RW or RAM and later copy the Video_TS folder to my computer hard drive for editing and DVD creation.

Considering that DVD recorders may soon become obsolete, I would like to know if there is any other device available which can accomplish the same thing without having to use a DVD recorder? In other words, a device that can be connected between the Cable Box and some type of external usb hard drive?

Thanks in advance for your help.

Impossible, the signal is scrambled.
