I have 5 receivers and one of my old DTV original TiVo models kept requiring a restart to bring it up and now finally that does not work any longer. I have one of the old SD "Directors Pack" receivers. I called DTV to deactivate the DVR and reactivate the SD receiver with the old smart card from the TiVo DVR but was told it could cause problems and I needed to just order a new one. I said no and deactivated it altogether but got to thinking maybe that was just the CS protocol to discourage such things. If I reactivate the smart card will it work in the SD Directors Pack receiver (the old small black boxes)? Thank you.
