I have a DTV system and am looking to buy a DVR to use as a TIVO. I bought a Toshiba RD XS-35 but could not get the system to talk to the DTV unit. I called Toshiba tech support and they didn't even have the specs on the 35. Called Best Buy (where I bought it) and their guy said they didn't think any unit does it. If anyone can point me toward a unit that is compatible with DTV I'd really appreciate it.
