I tried finding an answer to this, but I seem to get conflicting results. I have a VIP-612 and a VIP-211. If I pay the $40 activation fee to turn my VIP-211 into a DVR, can I take the drive from that to the 612 and watch the recordings there? Or do they have to be watched on the 211? Also, will the 211 DVR function just as the 612, or is it going to be different?
