Dual Destacker D575D Questions

[Joblcajo]

Moved into a apartment complex w/ sbche as the provider. Have two direct tv dvr's, my question is this, but keep in mind I am new to all this.
I understand that I need a destacker (Dual Destacker D575D) being both units have 2 inputs, is it possible to use one destacker for both units as in possibly splitting it some how? Really appreciate the help...
I found this diagram. could this work, but notice it is using the D575 dstacker not the D575D. Also where can I purchase the 2x4 multiswitch and the High frequency splitter, here is the link.... http://www.feldoncentral.com/TiVo/direcTV1destacker2DTV.gif

Take the two outputs of the D575D and connect to a 2x4 multiswitch. This will give you 4 outputs for use with DVRs. You have a dual destacker which is the equivalent of the high freq splitter and the single destacker. Here's one site for a bunch of multiswitches.

Would a 3x4 work instead of the 2x4?
