We do have DVR Advantage. But I'm a bit confused about the exemption you mention. We have four TVs. Two with the Dual DVR, two without. It would be easy enough to plug the phone line into the computer for the TV that doesn't have the DVR since it's in the same room.
Are you saying that the two TVs using Dual Tuner DVR is not subject to the charge at all and only the two others are if I don't connect to a phone line?
I don't understand what you're saying about cat5, 5e etc., or the bridge/router stuff.
Only dual tuner receivers are required to be connected to a phone line or broadband internet to avoid the $5 connection charge, as I recall. The primary receiver if a dual tuner is the one exempted from the requirement with DDA. Check with an E* CSR for your account. I'd do an online chat and ask and save the chat when completed in case you don't hook up the primary and they go ahead and charge you. I think it's better to just plug them into broadband internet if you have either DSL or cable internet. If you have DSL or cable internet you should have a router connected to the DSL or cable modem that serves as both a firewall and a means of connecting all the computers/devices in your home to the internet. Usually the router serves both wireless and wired devices. Wired devices are connected by cable (looks like telephone cable and comes in 3 basic grades Category 5, 5e, and 6) to the router by connecting the cable to the ethernet port of the device and one of the ports on the router. Wireless connections require a wireless bridge for the receiver to be able to connect to the router. Receivers like the 622 and 722 have a homeplug adapter built-in so you can also place a homeplug adapter kit at the electrical outlet into which the router is plugged-in to enable the receiver to connect to the router through your electrical cabling.
What receivers do you have? Not all are internet capable.
