I've got a HR20-700 and HR22-100 connected via ethernet to support multi room viewing. What would be the advantage of upgrading my system with SWMs, DECA adapters, etc to move to DirecTVs "supported" configuration for multi room viewing? Is it worth making the hardware investment ?

The advantage would be the relatively bulletproof nature of SWiM networking, plus the ability to add service to any room with only one wire.

DIRECTV's latest (non-DVR) receiver doesn't work without a SWiM and neither does its upcoming HR34 DVR. SWiM is "where it's going" and at some point without it, you'll be locked out.

Personally I think it's well worth it.

"Tough call"
If it's working fine now, it may not [will not] work any better.
I have DECA and it works fine, but then it did when I used ethernet.

Single wire has some pluses, as does not having a bunch of cables, but "function wise" if it's working fine now, then nothing is going to change by upgrading.

From the posts I've read the only Deca only one is the H25
the HR34 disables deca if an ethernet cable is plugged in

so the advantage would be D*'s support and easier CSR calls
I would upgrade to SWM just because it'll be easier
though for Deca if you already have ethernet cable in place and its working then there isn't an ROI

Nope, that's the H/HR24 that does.

then why does the HR34 even have a ethernet port?

My contract was up last month so when I feel strong enough to tackle DirecTV and dicker with them over my renewal, I am going to go from a perfectly functioning unsupported Ethernet WHDVR system to DECA and SWiM, but only if they give it to me for free. I think I'll win that argument. I've gotten free hardware before at contract renewal time.

The advantage of DECA over Ethernet is that it takes MRV off your home LAN.

Why? :shrug: but from what I've heard, connecting the ethernet port doesn't disable the internal DECA.

ok, I had seen a post to the contrary but maybe its just a programing oversight

The HR34 has an ethernet port because if it's used as an RVU server, and there are no other receivers in use, it can provide on demand and other services to the clients by connecting directly to a router. It's just one option.

It doesn't disable the Ethernet, at least presently.

But it is not recommended to use the Ethernet connection as a Broadband DECA, but it does seem to work, but again not recommended.

Also, "taking MRV off the home LAN" seems to be somewhat a myth. A robust Switch already does point-to-point, with virtually zero impact on the home LAN. But obviously, DECA is king and preferred for the typical home.

However you're likely to be connecting the Deca system to your network for VOD and such so that negates it for the most part

but it does give you a single point of contact which can be easier to manage

Ya
assuming they have a switch and not a hub (I've seen a few consumer routers with hubs listed as switches)(an easy way to tell is to use a computer with wireshark and plug it into an unused port, if you see data addressed for another device and not a broadcast packet then you have a hub, ok maybe not easy for others)

but from D*'s perspective its easier to support it, they don't have to train their people on RJ45 or run more cables through the home and they don't have to worry that someone is using a junky hub

Correct, DECA is mature, and the recommended and preferred approach.

I know I hate using consumer routers and if I ran a company I wouldn't want to put people in a place that they might have to troubleshoot some random crappy consumer router that isn't worth its weight in paper

so Deca has a nice ROI for D* I can't argue that, no added cable, no added training, and in time no extra devices

maybe they're leaving the ethernet on the HR34 on so it can take the place of the CCK/CCK-W's

Sorry, that's not it. It's more for its use as a server in an environment where there are no traditional receivers.

Was thinking the same as Stuart ... maybe an HR34 with a few Smart TVs, all Ethernet connected.

I know if I was D* that I'd want to simplify MRV setup
possibily have the HR34 replace the CCK/CCK-W when its used (ie if you have a HR34 maybe you can get rid of the CCK

but also have the ethernet link for use with the C30 type devices

why not kill 2 birds with one stone

maybe someone with a HR34 could test this (connect ethernet to the rj45 port and remove thier CCK)

I don't think anyone said it won't work (it will); it was mentioned that this wasn't the intended usage. I'm sure there will be stories of setups as you describe.
