OK, if you want the "why" --
Each recording is literally threaded through with references to the device which originated it. This is on purpose, so that programs can specifically not be moved from device to device. DIRECTV's encryption technology is the centerpiece of its entire technology. If they were not able to guarantee to content providers that their content could not be decoded and redistributed in pure digital form, they would have no ability to sign carriage contracts. Similarly, if they were not able to guarantee that only a DIRECTV receiver with a valid access card could watch DIRECTV programming, they would be unable to collect fees.
DIRECTV has always taken a very conservative line on this matter, unlike DISH which contends that it is strictly legal to do things like migrate recordings from device to device. DIRECTV's stance on this has led to far fewer legal battles attempted, and far less money paid to settle lawsuits and fulfill judgments.
Third party providers like TiVo and Sling do not record the pure digital signal (except where specifically allowed) and in TiVo's case even though they allow offloading it is of a transcoded signal that is significantly worse than the original. Sling does not create digital copies while it is streaming.
On the matter of DIRECTV-sanctioned placeshifting, such as is used by GenieGo, it takes place by replacing the original content protection with similarly strong content protection designed for mobile devices. DIRECTV is fairly late to the placeshifting game precisely because they acquired either concrete or de facto permission from content providers to do this.
From a technological point of view it would be possible for DIRECTV to safely decode and recode a recording so as to move it from one DVR to another, but it seems evident that they have determined two things:
(1) That the demand for such a service is not proportional to the cost of developing it;
(2) That such a service may require extensive contract changes which, again, require effort (i.e. cost) disproportional to the demand.
Finally I have reason to believe that such a service will become increasingly irrelevant as DIRECTV continues to develop its on-demand library and further integrates it with your DIRECTV service; losing a program that is recorded locally will be of no concern if you can stream that program from DIRECTV's servers.
I hope that answers your question to your satisfaction and I hope that you'll continue to ask questions if it doesn't. I'll continue to answer to the extent that I feel comfortable; my long-term relationship with DIRECTV is based on trust and there are some answers I don't feel comfortable giving.
