Somebody needs to explain to me and the others what additional / spurious network traffic this is imposing / causing on the DECA cloud. It actually looks like a good way to avoid one more Deca adapter and power supply for the broadband interconnect.
I may try it depending on the results of my installation tomorrow and report back.
(No conclusions in advance, but I'd bet there's no appreciable difference - it's a 100MB or GB switch.)
I haven't made the phone call yet to order this stuff yet (my disclaimer), but from a network perspective and how I /think/ this is working:
The negative is that the DECA device is negotiating one channel on the RG6 LAN (why are people calling this a cloud?). Let's say that channel has 100Mb of throughput. In theory the receiver needs all of that, when you split that bandwidth out to to other devices you are possibly limiting what is available to the receiver. Since there is no QoS *quality of service* built into most consumer switches, the second device could theoretically take needed bandwidth away from the receiver causing frame dropouts, frozen screens, etc. If you're sharing it to other devices that simply need internet, most likely your internet pipe itself will limit throughput to the other devices. My PS3, tv, HD-DVD, and HR20 will go on one switch connected to a DECA. They will be limited by the fact that my Internet is only 18Mbps, leaving 82Mbps for the receiver's video traffic.
Now, if you were to install a laptop on that switch and start copying 40Gb of movies/music from a local computer connected via a different DECA segment, you'll likely steal all the bandwidth and mess MRV up. DirecTV did not design this to be your all purpose network backbone.
Educating consumers on the effects that their other computer habits would have on MRV would be a nightmare, I don't blame D* for saying its not supported.
