For lurkers wondering - it is very easy. The swap to the SWM-8 is basically a move a cable at a time obvious
Yes - very easy - think I spent about as much time setting mine up as you did.
My gripe this weekend is that DirecTV sent me a new H20 and it appears to be one of the flavors that doesn't recognize the SWM8.
Looking at the picture of the SWM8, it specifies which Sats/voltages are connected to each input. How do you know which outputs of the WB68 to use?
I currently have cascaded WB68s. What I'd like to do is insert the SWM8 after the primary WB68, parallel to the secondary WB68 (each would use 4 ports). I would then connect one HR20 (which has only a single cable running to it) and an HDTivo (using 2 legacy ports). Does this sound like it will work?
Yes, that sounds like it would work. As for the four inputs, if you're connecting them to four outputs of a WB68 you don't need to worry - the SWM8 will "signal" the WB68 outputs so that they configure correctly to match the SWM8's needs.
