Tomorrow, an installer will be coming to upgrade my dish, and leave me with an HR20 so I can take advantage of the new HD goodness. I have a fairly complex system... 4 lines from the dish go to a 5x8 powered multiswitch. 4 lines go to two SD Tivos; The other 4 lines go to ANOTHER powered 5x8 multiswitch. 4 lines go to two more SD tivos; The other 4 lines run direct down to my home theater. These 4 lines go into a THRID powered 5x8 multiswitch that gives me 8 outputs in the AV cabinet. Currently, 4 of those are used (1 SD Tivo, 1 HR10-250), and 4 are "available" for quick connecting additional units for test, etc. I will use two of those "available" lines for the HR20. So, Let's see... that makes a total of 16 outputs, using 3 powered 5x8 multiswitches. Here's a diagram: My question... do I need DIRECTV to replace all three multiswitches with KAKU compatible units? If so, it doesn't look like the WB68 is a powered multiswitch; I suspect this will be an issue for the long runs / multiple cascades. What tyoe I switch do I need to make the installer use? My thoughts are that the installer should use a powered 12 output KAKU multiswitch in the attic (inputs from the dish), and then can use all of the existing lines. I think the 5x8 in the AV cabinet will also need to be replaced... but maybe an unpowered wb68 will work there? Is there a better way?
