I live in an apartment complex with DirecTV piped to every apartment from one main dish (through AT&T Home Entertainment), with a Hughes GAEBOA box. I have a single-tuner S2 in the bedroom with a GAEBO box and so far it's working fine. I have a dual-tuner TiVo in the living room and it's hooked up and has been working but as a single tuner only.

Here's AT&T HE's explanation of their setup:
AT&T Home Entertainment currently services apartment communities only. In a multi-dwelling unit setup, one satellite dish serves many units. In order to maintain signal quality over the long distance that the signal must travel from the satellite dish to the apartment, we "stack" the signal. This places the EVEN polarity of the satellite signal at 1550mhz-2050mhz, and leaves the ODD polarity of the satellite signal at 950mhz-1450mhz, allowing both polarities to share the same cable and be amplified/split to as many outlets as are provided at the apartment complex.

The Hughes GAEBOA already has a splitter between the wall and itself to SAT and ANT inputs on the GAEBOA. Putting a second splitter anywhere in this setup to try and make both tuners on the TiVo work causes me to lose my signal completely. AT&T Home Entertainment customer support advises that although they don't sell or provide DVR/PVR's nor officially provide DVR/PVR customer support, that what I need is something called a destacker (which is unfortunately $130-160) to make both tuners work on the TiVo. This is it:

I am hesitant to invest in this because it's pricy, and because it seems a little excessive to make this work. Then again, it seems silly to let my year of prepaid service on the dual-tuner TiVo go to waste by only utilizing it as a single-tuner.

Does anyone have any experience with this particular setup, and/or know whether this pricy destacker is the only thing that will make my dual-tuner TiVo function properly?

Your problem is that the GAEBOA has a destacker built in, but the DirecTV DVR with TiVo doesn't. Therefore the TiVo can only tune the odd transponders. You need to add a dual destacker to the line and then to the TiVo. Here's one http://www.solidsignal.com/prod_display.asp?PROD=SD575D from an online store. Make sure the one you get is a DUAL destacker, one on eBay describes it as one but is not.

Another solution is a single destacker used with a 2x4 multiswitch. This combination may be less expensive.

Thanks Jim for the info, but it's not a DirecTV DVR with TiVo. It's a standalone TiVo branded unit, dual-tuner S2.

Does that change what you've posted here?
