It is not possible to transfer files from one DVR to another except through the external hard drive (EHD), which only works for the 622/722 (/612?) household key.
The 522 and all earlier DVRs have USB 1.1 or so, IIRC, so the transfer rate if allowed would be very slow. You cannot record the TV ports, only the transport stream that comes from the satellite or the encrypted EHD.
Technically speaking, there are no ADCs to convert an analog signal into digital storage--it is one of the things that makes it different from some TiVos.
