I see the OP has 3 HR21-100's. If they put the 2-way splitters in between the DECA and the HR20's, those 3 BSF's won't be needed.

Looks to me like you'll need:

1- SWiM-16 + P.I.
6- DECA's + 1-DECA P.I. (5 HR's and the broadband connection)
1- 8way splitter (or 2- 4way's) to connect 6 DECA's to a SWiM-16
3- 2way splitters to connect your HR20-100's


Looking at the thread about connecting the HR20-100's, I see that the method that you suggest (without the BSF's) is not officially supported by Directv, but that it does work for most people. Should I insist that the installer put in the BSF's, or won't it really matter?

Since I have 5 DVR's (10 tuners), would I only need 1 8-way splitter (or 2 4-ways)? Is each output of a splitter capable of passing 2 tuners to each DVR in a SWiM setup?
Or, are you saying to get my 8 tuners from the 8-way, and the other 2 from the other SWiM-16 output?

Probably doesn't matter. If the installer has the BSF's, he can do it the "official" way. But if he doesn't have the BSF's and has the 2-way splitters, you can ask him to connect them the "unofficial" way, so as not to hold up your installation. Just my .02.

Yes. So you only need 1 output per device, including the DECA that will act as your broadband "bridge".

Ok, thanks, Steve.
I was a little confused on how many tuners vs. devices could be run from the splitters from these pictures:

So, in the case of the 2nd picture, there really is no need for a 2nd 8-way splitter, but by using both splitters it's possible to run 16 devices and potentially 32 tuners from the way it's drawn?

There is NO WAY you can have 32 tuners off a SWiM-16. The "16" refers to the maximum number of tuners, which for a DVR is two.
This means only eight DVRs can be connected to the SWiM-16.
There are two outputs and only eight tuners per output.

That's right. I forgot the SWiM-16 is really two DECA-bridged SWiM-8's, in the same case, so you can't put 10 tuners on an 8-way splitter connected to one "leg" of the SWiM-16. Max is 8 tuners per "leg", as VOS points out.

So for your configuration, you would need minimum of one 4-way splitter and one 2-way splitter. With each connector on the splitter good for one device, you can put put 4 DVR's (8 tuners) on the 4-way splitter connected to one leg of the SWiM, and 1 DVR (2 tuners) and the broadband DECA (no tuners, so "invisible" as far as the SWiM is concerned) on the 2-way splitter connected to the other leg of the SWiM.
