If the DVR is integrated into your DIGITAL cable or satellite receiver, directly receiving and recording the MPEG-2 stream, there is no loss of quality. If the DVR is hooked into the cable or satellite boxes OUTPUT. be it composite, S-video or component, these are analog decodes, and the signal must be re- encoded into MPEG-2 for recording. Hence loss of quality is inevitable with external DVRs, be it TiVo or otherwise.
