    This 72.5 routing is only true if you don't use the legacy ports on the SWM8 for locals.

    Some have mentioned problems (a while back) with the 4X8 legacy switches cascaded from the SWM8. Since you already have a 6X8 I wouldn't recommend purchasing the 4X8.

    I think I got it, fellas. Thanks for all the help.

    I'd like to ditch the old equipment now but sure don't want to pay for it....plus the wife HAS to have the HDVR2....the receiver she didn't want to switch to when she had to give up ultimate TV. :lol:

    One of your problems is you haven't learned how to count. 4HR2Xs is 8 tuners and a couple new single tuner models is 2 more tuners than a SWM can currently support. You will need a WB616 for 10 tuners.:):):)

    Or he can just leave the 6X8 in parallel with the SWM8...

    I'm not sure where I said I would be using both tuners on all 4 receivers. The one thing I did pick up on is that I can have 8 connections max. Since I'll already have the 6x8 connected I doubt I will disconnect it. Time will tell. Thanks, tho.

    Los...
    Just an additional note;

    In case the OP sees the need to you cannot actually "split" the feed from a 72.5 dish. You must run an additional line from the second unused output of the LNB mounted on the 72.5 dish to the flexport of the other multiswitch. That's two lines from the 72.5 dish with one going to flexport 1 on the SWM-8 and the other to flexport 1 on the WB68.

    But again the 72.5 locals are definitely going away and all this regarding it's dish's hookup options will soon be academic anyway...

    More good points...thanks.

    I looked at that diagram, DSW...helped tie it all together in my mind.

    One last question with this set-up. I can clearly see that the PI is after the SWM and inside coming off SWM1 output. I see there is also a SWM2....can each only power 4 tuners or can one power 2 and the other 6?

    I'm starting to think I'm just going to get 2 of these SWM-8s and be done with that part of it for a while.

    I remember when I thought it was a little dumb that anyone would need a HD Tivo - I was thinking that a guy could stand to watch recorded TV in SD...what a stupid thought.

    I kept looking around and think I answered my own question. It looks like you can purchase 1x8 splitters so all 8 tuners can be used off just SWM1....I think. It's odd to me that all capacity could be used through just one output but I don't have a clue how these things work.

    Not an expert on the 72.5 stuff by any means but I don't see why splitting the 72.5 output wouldn't work. It only uses half the transponders from 72.5 using 1 polarity. There for only a single output carries the entire signal that directv needs to use. Since it is always going to be the same thing it should be splittable just like you can split the 4 lines going into the switch as long as you match the inputs correctly.

    Thanks, Evan. For me it won't matter as I already have two cables coming off the dish and it would be just as easy to run one to each. Some others may find a final answer useful, though.

    I keep reading about SWM LNBs....I'm assuming I have this already with the slimline 5 but what exactly is this?

    Single Wire Multiswitch, or SWM, technology provides one coax output which can be split and distributed to multiple receivers/DVRs. If you have two (or more) coax coming from your Slimline dish, you do not have SWM. If you have an external multiswitch (WB68), you do not have SWM. You cannot use an SWM LNB with a second dish (either 72.5 for locals or 95 for international), because you must use an external multiswitch to combine the additional dish(es). To do that, you must have a non-SWM LNB assembly.

    I think what you are saying is that a SWM LNB is simply the SWM switch built in versus the external swtich. At first I thought the SWM LNB references were talking about the LNB being compatible with SWM equipment - not the actual switch itself.

    More than anything I didn't want to purchase one of these only to find out I need something else.

    Thanks, again.
